What China needs is countries that are willing to become the next independent powerful Iran to be given help to make 10-20 new Irans around the globe with the ability to cause major trouble for the usa.
The reason is China should not be the last man standing to fight Washington. There needs to be
many other headaches for Washington. This prevents war. If China is the only man left to stand up to Washington, then Washington wants war. The more free people in the world and free countries like Iran, the better for China.
Venezuela, Cuba, perhaps Argentina, Syria, Iran, even Lebanon and Iraq (with better leaders).
Bolivia has a cia military, so building up Bolivia's military is useless. Peru has a cia military too. These governments need to become free, including a free military loyal to Bolivia, not Washington before any defense development can be had.
A BRI 2.0 can be started. Where Chinese investors start factories in allied countries to displace the need for importing non-durable products from enemies of China. Say for instance Peru buys tissue paper from Canada. China starts a factory in Peru making tissue paper for the Bolivian market, jobs for Bolivians, less profits for Canada, and investment income for China. These three pillars for every new factory. Shaft the Anglos, reward allies of China, and profits for Chinese investors and owners.
