As the Trump administration yanks the US out of the Paris climate change agreement, claiming it will hurt the American economy, Beijing is investing hundreds of billions of dollars and creating millions of jobs in clean power.

China has built vast solar and wind farms, helping fuel the growth of major industries that sell their products around the world.

More than 2.5 million people work in the solar power sector alone in China, compared with 260,000 people in the US, according to the most recent annual report from the International Renewable Energy Agency.

While President Trump promises to put American coal miners back to work, China is moving in the opposite direction.

To help reach the 2030 goal, China is betting big on renewable energy. It pledged in January to invest 2.5 trillion yuan (367 billion US dollars) in renewable power generation -- solar, wind, hydro and nuclear -- by 2020.

Chinese authorities will roll out a new pollution alert system for regions ranging from the cleanest "green non-alert zones" to the most severe "red" zones, where the environment and natural resources are severely strained.

China's war on pollution has ramped up steeply this year, rattling the country's ports, commodities markets and factories across the country's smog-affected north. Even firms in higher-tech sectors like autos have started to take a hit.
