1.) China is negotiating its Regional Comprehensive Economic Partnership with all the Asia-Pacific TPP countries -> this is old news. Ever since the South China sea incidents/ruling, China has been acting belligerent towards all its neighbors, and as a consequence, most countries have shied away from China and towards US. thus the THAAD missile deploys in south korea, joint military exercises between Japan, US, Australia, and even closer relationships between Japan and South Korea. Less we forget, China's power is now fundamentally in the hands of one dictator - Xi, who grows closer to another dictator, Putin.
2.) One Belt, One Road project -> also old news. Ever since China's stock market crash, and the world finding out China's heavily indebted, supporting its state enterprises such as banks, steel and coal, it has no power nor finances to go abroad. This project has simply gone nowhere, much like supposed growing trade between China and Russia.
3.) China is now by several important measures the world’s largest economy, with about $4 trillion of reserves -> US is the biggest economy, period. the second biggest is US last year. China has now $3 trillion reserves and falling (and no one knows how much it really has, since it's covering up the capital outflows).
