China is still very much a continental power not a global power because it lacks the navy and the ability to project Sea power around the globe

It's navy still limited to the China Sea and can not go more than 1,000 miles from the Chinese coast

Also China has a massive demographic problem due to the impact of the one child policy and experiencing industrialization

When people's move to cities they stop having children and start having fewer of them

That has been the historical trend since the start of the industrial Revolution in 1769

The question is now will China's economic system and communist China survive the crisis

For China it's labor coast are becoming more expensive and nation's will look for cheaper sources of labour

The writer of prisoners of geography Tim Marshall in 2016 stated it would be 15 years before China could seriously challenge the US

I would say it would be a lot longer and that it's idiotic to challenge the US position as the global hegemon

Because they're prosperity depends on the international infrastructure created by United States

They should have waited another 50 years but China has the issue going from a population of 1.4 billion to a population of around 500 million
