passage: Climate change policy of the United States
Donald Trump, the 45th and current President of the United States, has said that “climate change is a hoax invented by and for Chinese.” During his political campaign, he blamed China for doing little helping the environment on the earth, but he seemed to ignore many projects organized by China to slow global warming.
