China would not take change in US policy on Taiwan lightly, Obama says

“For China, the issue of Taiwan is as important as anything on their docket,” Obama said at a news conference. “The idea of one China is at the heart of their conception as a nation and so if you are going to upend this understanding, you have to have thought through what ... the consequences are.”

China considers Taiwan a wayward province, to be taken back by force if necessary.
Obama noted that, under the decades-old policy, China had recognised Taiwan was its own entity that did things its own way, while Taiwan had agreed that, with some autonomy, it would not charge ahead and declare independence.
“That status quo, although not completely satisfactory to any of the parties involved, has kept the peace and allowed the Taiwanese to be a pretty successful ... economy and a people who have a high degree of self-determination,” Obama said.
