With the growing presence of Israeli companies in China and Taiwan it’s pretty hard to keep track. The China sector is a bit easier, since the there are websites out there to help Israeli businesses grow in China, and so most of the vital information can be found there. For an updated list of Israeli companies that are doing business in China, you might want to check out the list on the "Trade Mission to China, Embassy of Israel, Beijing" website. The Israel Export and International Cooperation Institute also has a pretty useful online China forum for business in China.

In the past year or so I’ve been trying to get my hands on some formal list of Israeli companies that are conducting business with Taiwan, but failed miserably. Thanks to a friend I unexpectedly got an outdated list this week, so I went through the entire thing and corrected it (as well as using it for my own personal ventures) and I’m posting it here should it be useful to anybody else but me :
