According to a legal friend who studies this area, it has been common 
practice for quite a while for the Chinese to require the licensing of 
Chinese-developed technology in many industrial areas in order for 
companies to have access to the market.  WAPI reportedly led to the 
highest-level conflict with US companies about this practice.
