Could Hong Kong & Macau be headed for full assimilation with Communist China?

In the late 1990's, the United Kingdom & Portugal surrendered their colony of both Hong Kong & Macau to the People's Republic of China under the Special Administrative Region provision. Hong Kong and Macau are prosperous city-states who will by the late 2040's be integrated with the rest of the Chinese Provinces. There have been anti-communism protests in Hong Kong with memorials being held annually for victims of the 1989 Tiement Square protests massacre by the Communist regime.

I believe that the UK & Protugal made a huge mistake by surrendering Hong Kong & Macau to the People's Republic of China. It's only a matter of time before the Chinese Army tries to use military force to destroy the sovereignty of Hong Kong & Macau. Military presence in Macau has increased since Portugal's surrender of Macau in 1999. There's more military presence in Macau today than there was under the far-right Estado Nuevo & 1974-99.

What should occur is making Hong Kong & Macau either self-sufficent in terms of national security & foreign policy or should the Confederate States of America emerge be C.S. states.
