Here's something you could try. 1. Find some reputable investors active in China. Start talks with them. 2. Contact the CEO and say "Thanks for pointing out to us the value of the Chinese market. We will now 1. move into the Chinese market (mention your talks to investors) and 2. proceed to sue you and your investors (who our legal team is contacting now). The alternative is that we set up a licensing deal (or that you pay us a 1-time fee to make this go away). Long term though my guess is that you should focus on your market and forget about China.
