We can clearly see that the so-called "Taiwan Issue" is not on the front burner now in Chinas Mainland nowadays.  From General Secretary Xis  three-and-a-half-hour speech on the 19th plemun, in which only 600-odd words are concerning Taiwan, China is now focusing on her strategies of international relationship, stablizing her finance and currency, advancing to a wealthy society, erasing the gap between the haves and the have-nots, setting a sounder housing policy, building up Chinas own brand names and R&D, and so on. 

Mr. Xi, as well as people of Chinas Mainland, has full self-confidence that final unification is a sure thing.  Taiwan is there, what China Mainland has to do is to follow her established schedule, step by step, not in a hurry, and take a close watch on Taiwan, that is.  Therefore, dear islanders, you can rest assured that there wouldnt be "adverse" change on Taiwan after Trumps state visit to China, such as the 4th communique regarding Taiwan because you are put on the back burner now for China and America.
