On the domestic front, the world's second largest economy had already emerged as a renewables powerhouse, outstripping the United States.

The International Energy Agency (IEA) estimates that China holds 3.5 million of the 8.1 million renewable energy jobs globally, compared to less than 800,000 in the United States. China's National Energy Administration said the nation's renewables sector would generate at least 13 million jobs by 2020.
But US and European entrepreneurs "should still have an advantage" when it comes to high tech, he added, pointing to thin-film solar, and cutting-edge engineering services as examples.
In 2016, China boosted its overseas influence by establishing the Asia Infrastructure Investment Bank. It is also funnelling billions into the New Development Bank, set up by the BRICS nations Brazil, Russia, India, China and South Africa.
