Washington: President Donald Trump has accused the previous Obama administration of waging a "relentless war" on American energy by reaching "ineffective" global agreements that he alleged allowed the world's worst-polluting countries to continue their practices.

His statement came amidst claims by Environmental Protection Agency's administrator Andrew Wheeler that the landmark Paris Agreement on climate change is unfair to the US and countries like India and China benefit out of it. For years, politicians told Americans that a strong economy and a vibrant energy sector were incompatible with a healthy environment. In other words, one thing doesn't go with the other.
