Taiwan companies have been allowed to invest in China and Taiwan tourists have been welcomed by the Mainland ever since China's open door policy was initiated in later 70s, but Taiwan had not been able to do the same very recently.

With the relationship between Mainland and Taiwan was warmed up since last year, Taiwan is also opening its door to the Mainland.  From July last year to early April, after the two sides agreed to allow mainland tourist groups to travel to Taiwan in June last year, more than 174,000 Mainland tourists have visited Taiwan.  A lot more is expected this year.
