The actor and environmentalist, who called for action to combat climate change during his Oscar acceptance speech last month, praised China's shift toward renewable forms of energy to lower carbon emissions.
"As we all know, the United States and China are the two biggest contributors, and I think that China has made radical movements forward as far as alternative energy and ways to be sustainable," he said at a news conference.
DiCaprio was in Beijing to promote "The Revenant," which won him his first Oscar, for best actor, at this year's ceremony. The movie was released in mainland China on Friday and has already earned 100 million yuan (USD 15 million) at the Chinese box office, according to an announcement at today's news conference.
China is the world's largest coal user and producer, but has also become a leading investor in renewable forms of energy, such as solar and wind power.
