Ask China: How does China tackle environmental issues?

What achievements has China made in tackling pollution? What's the magic behind China's growing vegetation cover? Does Beijing's odd-even license plate system work to curb smog? These are some of the common questions that come to the fore whenever China's environmental issues are discussed. In this episode of Ask China, a special series focusing on important subjects related to China, CGTN invited Wu Changhua, a policy analyst and adviser on sustainability strategy and innovation, to answer some of the most straightforward questions we have collected from people around the world.
