Source article in Chinese: 2013年中国对美的探底式外交
By He Qinglian on November 30, 2013
While the Sino-US diplomatic relation is still
far from sabre-rattling, it is obvious that China intends to
test the bottom line of the US. By testing the bottom line I mean
China's approach of continually pushing the boundary of its
adversary. If its adversary yields, China would tentatively push
further. This bottom-line testing of Beijing is not an ad hoc action
taken on a whim, rather, it is a strategy developed a long time
ago.
