Then it is time for PLA to move in.
The Chinese have a long term strategy:
Mr Xi holds that China will remain permanently governed through a Leninist party controlling a one-party state. To suppose, as many in the west have, that China will gradually transform into something approaching a Singaporean or western-style democracy is the stuff of dreams.
Mr Xi outlines two grand objectives: from 2020-2035, China will become a fully modern economy and society; this to be followed by a further 15 years to 2050, when Chinas quest for national wealth and power will come to fruition as it assumes great power status. This coincides with the centenary of the foundation of the Peoples Republic in 1949. By then, Mr Xi plans for China to have become a global leader of composite national strength and international influence.
