I will express my opinion before the discussion turns to politics, and the long-suffering moderators are forced to close the thread.
If Asian countries are really interested in "containing" China's expansion so as not to suffer the fate of Hong Kong's citizens, their only chance is to use the economic weapon. Any attempt to form some kind of military alliance will not work, the United States has already shown in Vietnam, Iran and Afghanistan that it is not a reliable ally.
China's weaknesses are the financial situation of its banks, exposed to the failure of a poorly planned real estate policy, the supply of hydrocarbons, the mobility of its merchant fleet and the operation of its logistics bases located in foreign ports, a machinery that is very sensitive to delays due to external causes.
A global campaign against Chinese goods and services could be devastating to its production and export system, with a good chance of creating the implosion of the entire economic structure.
I do not consider myself qualified to advise the most appropriate tactics to achieve these objectives, but perhaps the memory of the enormous losses suffered by humanity due to the virus, may move some countries to initiate a series of compensation claims. That would be a good start, but I wouldn't expect any help from the USA, in this kind of struggle for freedom it would be a group of sardines devouring a shark.
A confrontation of wills, rather than weapons.
