Experts at a private Taiwanese security company decided to pull out of a security conference in Las Vegas after coming under what was described as pressure from Chinese and Taiwanese agencies.

Wayne Huang, chief technology officer and founder of Taiwanese security vendor Armorize Technologies, and Jack Yu, a researcher at the company, were scheduled to give a talk on Chinese cyber warfare capabilities at the Black Hat USA 2010 security conference, which will be held in Las Vegas on Wednesday and Thursday next week.
