China and the United States agree that stronger pledges to fight climate change should be introduced before a new round of global talks at the end of the year, the two countries said in a joint statement on Sunday.
"If we can all hold to 1.5 [Celsius], we're setting a good example for a lot of other countries as they make choices", Kerry told The Washington Post during a visit this month to India.
China says President Xi Jinping has agreed with leaders of France and Germany to strengthen their cooperation on climate change.
The joint statement came after a trip to Shanghai by United States climate envoy John Kerry, the first official from Biden's administration to visit China, signalling hopes the two sides could work together on the global challenge despite sky-high tensions on multiple other fronts.
The scheme is seen as a key part of the EU's Green Deal, an ambitious push to achieve carbon neutrality by 2050 and meet the targets of the Paris Climate Agreement.
During a video meeting with German and French leaders on Friday (Saturday NZT), Xi also said that climate change "should not become a geopolitical chip, a target for attacking other countries or an excuse for trade barriers", though he called for closer cooperation on the issue, according to the official Xinhua News Agency.
"We've had too much coal, other countries have too much coal, but China is the biggest, biggest coal user in the world", he added.
Xi past year announced that China, the world's biggest emitter of greenhouse gases, would achieve a peak in carbon dioxide emissions before 2030 and carbon neutrality by 2060.
Major emitters of greenhouse gases are preparing for the next United Nations climate summit taking place in the UK in November. Countries pledged then to limit global warming to "well below" 2 degrees Celsius (3.6 Fahrenheit) above preindustrial levels and possibly keep to 1.5 degrees Celsius.
It listed multiple avenues of climate cooperation between the world's top two economies which together account for almost half of the greenhouse gas emissions responsible for climate change.
The two also said their countries would take short-term actions, such as helping developing nations fund the transition to more sustainable energy sources and phasing down production and consumption of hydrofluorocarbons, a particularly potent greenhouse gas.
