Speaking in the House of Lords on 30 June 2025

Debate

Deep Sea Mining in International Waters

Contribution

My Lords, as a party to the UN Convention on the Law of the Sea, the United Kingdom fully supports the work of the ISA. The UK has been fully engaged in the work of the ISA since it was established, following the entry into force of UNCLOS in 1994. There are strong protections in place against deep sea mining around Diego Garcia. Under the agreement, the United Kingdom has the right to exercise rights and authorities required for the long-term secure and effective operation of the base out to 12 nautical miles and is responsible for environmental protection on Diego Garcia. Additionally, we negotiated a further 12 nautical-mile buffer zone out to 24 nautical miles, in which Mauritius cannot place any maritime installations, sensor structure or artificial island that might be required for subsea mining without UK consent.
