Here peace deal is intended to include an observed cease fire. If only a cease fire is announced I will wait seven days before closing the market and resolving yes. If the cease fire breaks down within that period the question will not resolve, but will remain open.

(I have not created many markets. This seems reasonable and interesting to me but if experienced creators think this is a bad way to run the market I will consider changing it)

All three parties (PRC, Ukraine, Russia) must publicly announce, assent to, and agree that China is involved in, the peace deal. They do not need to be physically present in the same room with flags when they do so.

Resolution will be based on credible news reports, or government statements.
