Hangzhou may be impetus for sustainable development

Leadership shown by G20 members on tackling climate-change challenges will promote sustainable development and speed up ratification of the Paris Agreement, experts said.

"G20 members should take the lead to help bring the Paris Agreement on Climate Change into force as soon as possible," said President Xi Jinping at a media conference on Monday, after the two-day G20 Summit.

Xi's comments came after G20 members reached consensus on a number of key issues facing the world. Tackling climate change has been a hot-button issue for both developed and developing economies.
