Taiwan is again asking the UN to let it take part, framing peace in the Taiwan Strait as something the whole world's economy depends on — a direct challenge to Beijing.

• Taiwan's foreign ministry laid out three demands ahead of the UN General Assembly, which opens September 8 in New York.
• The core argument: UN Resolution 2758 never actually barred Taiwan from taking part, and China has twisted it to claim it speaks for Taiwan's 23.5 million people.
• Taiwan says it will keep the status quo and settle disputes peacefully, and that any attempt to change that by force breaks the UN's own charter.
• The pitch leans on economics — the Taiwan Strait is one of the world's busiest shipping routes and a lifeline for global supply chains.
• Taipei points to China's military intimidation, cyberattacks and economic pressure, plus a new Chinese law passed in July that reaches across borders to silence critics abroad, which has drawn concern from the US, EU and Australia.

Outlook: Allied countries will again write jointly to the UN secretary-general and speak up for Taiwan during the late-September debate, but China's veto power means nothing changes at the UN itself.
