Here at the 22nd annual U.N. climate change summit, known as the Conference of Parties, or COP 22, China’s Vice Foreign Minister Liu Zhenmin has rejected Donald Trump’s claim that global warming is a Chinese hoax. Instead, Liu Zhenmin said, “If you look at the history of climate change negotiations, actually it was initiated by the IPCC with the support of the Republicans during the Reagan and senior Bush administration during the late 1980s.”
