Do you know if Taiwan pass U.S. beef import, Taiwan will be able to depending on U.S.A. for TIFA and maybe TPP. Taiwan will be good friend with U.S.A. and maybe one day they will be like Japan and South Korea and let U.S. military staying within their territory.
Why do you think Taiwan has to do this?
Because your ECFA is not giving Taiwan any trading edge advantage anymore than with Japan and South Korea, and therefore Taiwan has to depends on U.S. in order to have more trading advantages over Japan and South Korea.
Please, you can reverse this and prevent this to happens. You have to give Taiwan more trading advantages over Japan and South Korea.
