Tom stop scare mongering There are very real barriers to Chinese expansionism in the west and south west. As to designs on Taiwan, they simply want what was once theirs back, but these days they look upon it as an automonous economic zone, as long as it stays quite militarally they will leave it alone because it is Taiwan business that has fueled chinese expansion. The border with China and India is not fixed and in dispute but no one is going to war over a pile of rocks and snow. China builds inferstructure as a means of economic expansion and keeping its population employed, you could learn from them, with a population growing as quickly as there's nation building is an imperative

We need to keep our attention on rogue state NK, not on China
