China Coast Guard Patrol near Senkaku/Diaoyu

  • A China Coast Guard ship formation passed through waters around the Senkaku Islands (administered by Japan; called Diaoyu by China).

  • China described this as a “rights enforcement patrol”, claiming the operation was lawful to uphold its rights and interests.

  • The Senkaku/Diaoyu Islands are a long-standing maritime dispute between China and Japan.

Trigger for Escalation

  • Tensions escalated after Japan’s Prime Minister Sanae Takaichi stated in Parliament (7 November) that a hypothetical Chinese attack on Taiwan could trigger a military response from Japan.

  • China reacted angrily, signalling that it expects Japan to retract or modify these remarks.

Positions of the Parties

  • China:

    • Claims Taiwan as its own territory.

    • Does not rule out use of force to achieve unification.

  • Taiwan:

    • Rejects Beijing’s sovereignty claims.

  • Japan:

    • Administers the Senkaku Islands.

    • Increasingly vocal about Taiwan’s security implications for Japan.

      

Senkaku Islands

  • The Senkaku Islands are a group of small, uninhabited islands in the East China Sea that have been the subject of a long-standing territorial dispute between Japan, China and Taiwan.

  • The islands are strategically located near important shipping lanes and rich fishing grounds, and may also have oil and gas reserves under the seabed.

  • The sovereignty over the islands has implications for the security and economic interests of the claimants, as well as for regional stability and order in East Asia.
