The US, Japan, and South Korea jointly restated their support for peace in the Taiwan Strait, a diplomatic win for Taiwan and a warning to Beijing against changing the status quo by force.

• Secretary of State Marco Rubio and his Japanese and South Korean counterparts met on the sidelines of the UN General Assembly and issued a joint statement backing Taiwan Strait stability.
• The statement opposes any one-sided attempt to change the status quo and supports Taiwan's meaningful participation in international organizations.
• Taiwan's foreign ministry welcomed the move, saying it shows Taiwan Strait security is now a broad international consensus, not just a US concern.
• Taipei tied the issue to money as well as security: a stable strait matters for the global economy and supply chains, which run heavily through Taiwan's chip industry.
• Taiwan said it will keep building up its own defenses and deepen cooperation with the US, Japan, South Korea, and other democracies.

Outlook: Expect Taiwan to lean on this three-way backing to push harder for a seat at international bodies, while China is likely to push back against what it sees as outside interference.
