I was going to write a pretty massive summary of this, but basically, while it may seem like something rather minor, this is actually a massive thing for the 2 (arguably 1 to some) nations that I can't even describe for those who don't know the history of 1900's China and the Post WW2 removal of the Republic leadership from the mainland by the Communist forces at the "end" of the civil war.
It's not without controversy, people in Taiwan are protesting in the streets as, even before this, Ma Ying-Jeou has proven to be an unpopular president in Taiwan, but I await to see what, if anything actually comes out of this.
