Tonga Weighs New Deep Sea Mining Deal Amid Earthquake

In-Depth Analysis

Tonga's potential new contract with The Metals Company (TMC) is under review against a backdrop of evolving international regulations and environmental concerns. The existing contract, signed in 2021, allows mining activity in Tonga's designated area within the Clarion Clipperton Zone (CCZ) under the ISA framework. However, TMC is also exploring mining through a US pathway, which sits outside international laws.

Civil Society Forum of Tonga is advocating against the new contract, citing risks to Tonga. According to Drew Havea, Tonga, as the sponsor country, would be liable for any environmental damages caused by mining activities. Lori Osmundsen's legal review further emphasizes that a new contract similar to Nauru's agreement with TMC could expose Tonga to legal risks and breaches of the UN Convention on the Law of the Sea.

The ISA is currently investigating contractors, including TMC, for potential breaches of their exploration permits. This scrutiny adds another layer of complexity as Tonga considers its next steps.

Adding to the situation, a 5.2 magnitude earthquake occurred near Nuku'alofa, though no tsunami threat was issued. This event underscores the natural vulnerabilities facing Tonga, potentially influencing the government's decision on the deep sea mining contract.
