Taiwan is standing firm on joining this year's APEC leaders' summit in China, despite Beijing's attempts to downgrade its status — a win for Taiwan's international standing and a headache for China's diplomatic image.

• Taiwan will send Acer founder Stan Shih as its representative to the APEC summit in Shenzhen in November, even as China's Taiwan Affairs Office insists Taiwan's participation must follow the "one China" framework.
• Sources close to the matter say Taiwan sees this year's meeting as especially important given global supply chain risks and economic uncertainty, and will not give up its membership responsibilities just because China tries to make things difficult.
• If China breaks the promises it made to all member economies when bidding to host — guarantees that everyone's rights would be protected — it would expose Beijing's disregard for international rules and norms.
• There's a pointed warning that if Russia's Putin and North Korea's Kim Jong Un show up at the summit alongside China, it would only reinforce the image of a China-Russia-Iran-North Korea bloc.
• The message frames this as a test of whether China acts like a country that genuinely welcomes the world or one that keeps the door only half open.

Outlook: Watch whether China follows through on its guarantees to member economies, and whether high-profile attendees like Putin or Kim show up, which could further damage China's diplomatic standing going into the summit.
