China does not have that much of a problem with the status quo. The status quo with the One China Policy has worked very well for decades. In fact, 2015, right before the DPP got to power, could be regarded as the height of cross-straight relations. Things only started going sour after the DPP started making moves towards true independence, and after the US sent increasing numbers of warships to China's back yard.

It is not China that is deviating from the status quo.
