BEIJING -- Chinese President Xi Jinping on Thursday said it requires "extraordinarily hard efforts" for China to fulfill its commitment to moving from carbon peak to carbon neutrality, which is in a much shorter time span than what might take many developed countries.

Xi made the remarks while addressing the Leaders Summit on Climate via video link from Beijing.

China will strive to peak carbon dioxide emissions before 2030 and achieve carbon neutrality before 2060, Xi noted.

"This major strategic decision is made based on our sense of responsibility to build a community with a shared future for mankind and our own need to secure sustainable development," Xi said.
