The five countries bordering the Caspian Sea – Azerbaijan, Iran, Kazakhstan, Russia, and Turkmenistan – have signed a landmark agreement defining the sea's legal status, resolving disputes ongoing since the Soviet Union's collapse. The treaty designates 15 nautical miles from the coastline as sovereign waters, with an additional 10 nautical miles forming an exclusive economic zone for fishing. Areas beyond this are considered common waters. It clarifies maritime boundaries and addresses conflicts over oil and gas fields.

The agreement prevents Caspian nations from allowing military presence of third-party aggressors like the US and NATO in Caspian waters and avoids governance under the United Nations Convention on the Law of the Sea (UNCLOS). The treaty allows member nations to construct pipelines with the consent of affected neighboring states and governs seabed reserve development through separate deals adhering to international laws. The Caspian Sea is rich in oil, gas, and caviar.

Introduction

The Caspian Sea Breakthrough: A Treaty Defining a Region's Future

The signing of the Convention on the Legal Status of the Caspian Sea by Azerbaijan, Iran, Kazakhstan, Russia, and Turkmenistan represents a pivotal moment in the geopolitics of the region. This agreement, years in the making, aims to resolve the complex legal ambiguities that arose following the dissolution of the Soviet Union in 1991, which had previously managed the sea's affairs alongside Iran. The primary objective of this agreement is to establish clear guidelines for the division and utilization of the Caspian Sea's resources, addressing concerns about sovereignty, resource exploitation, environmental protection, and security.

A Sea of Contentions: Historical Roots of the Dispute

The Caspian Sea, often referred to as the world's largest inland body of water, holds immense strategic and economic significance. Its shores border five nations, each with its unique geopolitical ambitions and economic interests. The collapse of the Soviet Union fundamentally altered the power dynamics in the region. Prior to 1991, the Caspian Sea was largely governed by treaties between the Soviet Union and Iran, established in 1921 and 1940. These treaties, while effective during the Soviet era, did not adequately address the needs and aspirations of the newly independent states of Azerbaijan, Kazakhstan, and Turkmenistan.

The primary bone of contention revolved around whether the Caspian Sea should be classified as a sea or a lake. This seemingly semantic distinction has profound implications under international law. If classified as a sea, the United Nations Convention on the Law of the Sea (UNCLOS) would apply, potentially granting rights of passage and resource access to nations beyond the littoral states. If classified as a lake, the Caspian Sea would be subject to different legal principles, necessitating agreement among all five bordering nations on resource division and usage.

The divergent interests of the five Caspian nations further complicated the situation. Azerbaijan, with its burgeoning oil and gas sector, sought to maximize its resource exploitation and export opportunities. Kazakhstan, similarly rich in hydrocarbons, aimed to attract foreign investment and develop its energy infrastructure. Turkmenistan, possessing vast natural gas reserves, aspired to become a major energy exporter. Russia, keen on maintaining its influence in the region, advocated for solutions that preserved its strategic interests and ensured its control over key energy transit routes. Iran, with its relatively smaller share of Caspian Sea resources, emphasized the need for equitable distribution and environmental protection.

These conflicting interests led to protracted negotiations that spanned over two decades. Numerous summits, working groups, and bilateral discussions were held to bridge the gaps and forge a consensus. The primary sticking points included the delimitation of maritime boundaries, the allocation of seabed resources, the regulation of fishing rights, and the management of environmental risks.

Key Provisions of the Convention

The Convention on the Legal Status of the Caspian Sea represents a compromise that balances the competing interests of the five littoral states. While it does not explicitly define the Caspian Sea as either a sea or a lake, it establishes a unique legal regime tailored to its specific characteristics.

  • Territorial Waters: The convention establishes a 15-nautical-mile zone of territorial waters extending from each country's coastline. Within this zone, the coastal state exercises full sovereignty, including the right to regulate navigation, fishing, and resource exploitation.

  • Exclusive Fishing Zones: Beyond the territorial waters, a 10-nautical-mile exclusive fishing zone is established. Within this zone, the coastal state has exclusive rights to regulate fishing activities and conserve marine resources.

  • Common Waters: The remaining waters of the Caspian Sea, beyond the territorial waters and exclusive fishing zones, are designated as common waters. In these waters, all five Caspian nations have the right to navigate, conduct scientific research, and lay submarine cables and pipelines, subject to certain conditions.

  • Seabed Delimitation: The convention provides a framework for the delimitation of the seabed for resource exploitation purposes. It stipulates that the seabed shall be divided into sectors based on agreements between adjacent and opposite states, in accordance with principles of international law.

  • Pipeline Construction: The convention addresses the issue of pipeline construction across the Caspian Sea. It states that pipelines can be laid with the consent of the states through whose sectors the pipeline will pass, without requiring the approval of all five Caspian nations.

  • Military Presence: A significant provision of the convention prohibits the presence of armed forces belonging to non-Caspian nations in the Caspian Sea. This provision is aimed at preventing external powers from gaining a foothold in the region and potentially destabilizing the security environment.

  • Environmental Protection: The convention emphasizes the importance of environmental protection and sustainable development in the Caspian Sea. It calls for the Caspian nations to cooperate in monitoring and managing environmental risks, preventing pollution, and conserving biodiversity.

Analyzing the Key Actors

The Caspian Sea agreement is the culmination of years of negotiations between the five littoral states. Each country had its own set of priorities and concerns, which shaped its approach to the negotiations.

  • Azerbaijan: Azerbaijan, heavily reliant on its oil and gas exports, sought to secure its rights to explore and develop its offshore hydrocarbon resources. It also aimed to resolve its territorial disputes with Iran and Turkmenistan over certain oil and gas fields. Azerbaijan played a key role in advocating for the construction of pipelines across the Caspian Sea to transport its energy resources to European markets.

  • Iran: Iran, with a relatively smaller share of Caspian Sea resources, emphasized the need for equitable distribution and environmental protection. It also sought to prevent the presence of foreign military forces in the Caspian Sea, viewing it as a potential threat to its national security. Iran advocated for a collective decision-making mechanism that would give all five Caspian nations a say in the management of the sea's resources.

  • Kazakhstan: Kazakhstan, rich in oil and gas reserves, aimed to attract foreign investment and develop its energy infrastructure. It supported the construction of pipelines across the Caspian Sea to diversify its export routes. Kazakhstan also sought to ensure the free passage of its vessels through the Caspian Sea and access to its fishing resources.

  • Russia: Russia, with its strong military presence and strategic interests in the region, sought to maintain its influence in the Caspian Sea. It supported the principle of consensus-based decision-making and opposed the presence of foreign military forces. Russia also aimed to protect its existing energy transit routes and prevent the emergence of competing pipeline projects.

  • Turkmenistan: Turkmenistan, possessing vast natural gas reserves, aspired to become a major energy exporter. It sought to secure its rights to develop its offshore gas fields and construct pipelines to transport its gas to Asian and European markets. Turkmenistan also aimed to resolve its territorial disputes with Azerbaijan and Iran over certain oil and gas fields.

Analyzing the Key Actors

The Significance of Avoiding UNCLOS

One of the most significant aspects of the Caspian Sea Convention is its deliberate avoidance of governance under the United Nations Convention on the Law of the Sea (UNCLOS). UNCLOS, adopted in 1982, provides a comprehensive legal framework for all marine and maritime activities, including the delimitation of maritime boundaries, the regulation of navigation, and the management of marine resources.

However, the Caspian nations collectively decided that UNCLOS was not suitable for the unique characteristics of the Caspian Sea. Several factors contributed to this decision:

Advertisement
  • Enclosed Water Body: The Caspian Sea is an enclosed water body, not directly connected to the open ocean. This distinguishes it from most other seas and oceans, which are subject to the provisions of UNCLOS.

  • Unique Legal History: The Caspian Sea has a unique legal history, with its governance traditionally based on agreements between the littoral states rather than international conventions.

  • Geopolitical Considerations: The Caspian nations were wary of granting rights of passage and resource access to non-Caspian states, which could potentially undermine their sovereignty and control over the sea's resources.

By avoiding UNCLOS, the Caspian nations were able to create a legal regime tailored to their specific needs and interests. This allowed them to maintain control over the Caspian Sea's resources, prevent foreign interference, and promote regional cooperation.

The Significance of Avoiding UNCLOS

The Role of Organizations and Legal Frameworks

While the Caspian Sea Convention is the primary legal instrument governing the Caspian Sea, other organizations and legal frameworks also play a role in shaping the region's affairs.

  • United Nations: The United Nations, as the preeminent international organization, plays a role in promoting peace, security, and sustainable development in the Caspian Sea region. The UN can provide a forum for dialogue and cooperation among the Caspian nations and assist them in addressing common challenges, such as environmental protection and maritime security.

    Advertisement
  • International Maritime Organization (IMO): The IMO, a specialized agency of the United Nations, is responsible for promoting safe, secure, and efficient shipping on international waterways. The IMO can provide technical assistance to the Caspian nations in developing and implementing maritime safety regulations and promoting the sustainable use of marine resources.

  • Regional Organizations: Several regional organizations, such as the Shanghai Cooperation Organisation (SCO) and the Economic Cooperation Organization (ECO), also play a role in promoting cooperation and development in the Caspian Sea region. These organizations provide platforms for dialogue and collaboration on issues such as trade, transport, and energy security.

In addition to these organizations, various international legal frameworks, such as the Convention on Biological Diversity and the Ramsar Convention on Wetlands, are relevant to the Caspian Sea region. These frameworks provide guidelines for environmental protection and sustainable resource management.

The Role of Organizations and Legal Frameworks

Stakeholder Positions and Underlying Interests

The Caspian Sea Convention reflects a complex interplay of stakeholder positions and underlying interests. Each of the five Caspian nations has its own set of priorities and concerns, which shaped its approach to the negotiations.
