“What raw materials are those then?”
Well, you know, economic statistics like that are available with a couple punches on your keyboard:
“The top imports of China are Crude Petroleum ($150B), Integrated Circuits ($144B), Iron Ore ($99B), Cars ($42B), and Soybeans ($37.4B), importing mostly from Japan ($133B), South Korea ($131B), United States ($122B), Germany ($106B), and Chinese Taipei ($104B).”

China is currently importing more and increasing amounts of their crude from Russia not America.
America is too busy begging Venezuela and the Saudis to sell us oil as it is.
And the $122 Billion in imports from the US is totally trumped by huge Chinese exports to the US.
