Taiwan is pushing harder for a seat at the UN table, framing its exclusion as a risk to global security rather than a narrow diplomatic complaint.

• Taiwan's foreign minister Lin Chia-lung published an essay in an influential Brazilian political and business outlet read by government officials and lawmakers.
• The core argument: authoritarian states are rewriting global rules, and the UN Charter's basic principles are being tested.
• China is accused of twisting the 1971 UN resolution 2758 to lock Taiwan out of international bodies — and to build a legal excuse for future military action in the Taiwan Strait.
• Taiwan pitches itself as the front line of democracy and the Taiwan Strait as a lifeline for global supply chains, making peace there everyone's business.

Outlook: Expect more of this quiet outreach to Latin American elites as Taiwan tries to widen support ahead of and beyond this UN General Assembly session.
