However, he sees that a long-game is being practiced by the enemies of the US-led Empire that is out to control the world.
It seems that the Chinese leadership has concluded that the Trump Administration is determined to use its full spectrum radical leverage to hobble China as a rival, and to resurrect its own global domination – Xi seems to foresee a long struggle for position in the global future: one that will be played out geo-politically (in the jostling in the South China Sea, over North Korea, Taiwan and the BRI), as much as in the economic domain. If this is so, there is real risk of the ‘jostling’ spontaneously escalating into a military clash, whether limited and contained, or not.He is wrong about Trump's administration starting this economic war. He only accelerated it. It started in the Obama administration under the "pivot to China" policy, but it wasn't Obama who instigated it. Obama, like most government officials, was merely a puppet. It was primarily the Anglo-American ruling capitalist classes that have since WWII established their power over much of the world. However, the latter won't suffer in this war--it is the workers of nations controlled by the Empire that will be the causalities in this new economic war.
