The world's top two carbon polluters, the USA and China, issued a statement on Saturday saying the two nations are committed to fighting together against the climate crisis.

The joint statement by the two nations read, "The United States and China are committed to cooperating with each other and with other countries to tackle the climate crisis, which must be addressed with the seriousness and urgency that it demands."

The joint statement comes after the US's climate envoy John Kerry visited China. Kerry is the first US representative to visit China from the Biden administration.

The two countries will develop long-term strategies to become carbon-neutral.

China has already set a goal to be carbon-neutral by the year 2060.

The two global superpowers also plan to increase investment in green energy in developing nations including the use of Hydro Flouro Carbons used in refrigerators.
