Earlier quoted context omitted.
Western countries irrevocably recognizing Taiwan would be a start.
It's an interesting idea, but it would amount to calling China's bluff. China has stated that they would definitely commit to a ground invasion of Taiwan if the US recognized it. The question is -- how serious are they about that? Personally, I think they'd go for it. They've been itching to take over Taiwan by force anyway.
I don't believe this is true. IIRC they've implied they would invade if Taiwan declared itself independent.
