Chinese President Xi Jinping on Saturday called for a "smooth transition" in Beijing's relationship with Washington and praised outgoing President Barack Obama for strengthening ties between the two nations, Reuters reported.
During a meeting in Peru, Obama repeated the U.S. urging that all sides in the dispute over the South China Sea reduce tensions and resolve their disputes peacefully.
The meeting is expected to be the last between the two leaders before President-elect Donald Trump enters the White House. Trump has been sharply critical of China.
"We meet at a hinge moment in the China-U.S. relationship," Xi said at the start of the meeting, through an interpreter.
"I hope the two sides will work together to focus on cooperation, manage our differences and make sure there is a smooth transition in the relationship and that it will continue to grow going forward," he said.
Trump, a Republican, has accused China of being a currency manipulator and promised to slap big tariffs on imported Chinese goods. He has also called climate change a "hoax" designed to help Beijing.
"The concept of global warming was created by and for the Chinese in order to make U.S. manufacturing non-competitive," Trump wrote in a tweet in 2012.
Obama and Xi pushed for the international community to back an agreement forged in Paris to combat global warming. Obama called that an example of the benefits of the two countries working together.
"Now we face the work of making sure our economies transition to become more sustainable," he said.
Trump's election has raised questions about whether the United States would try to pull out of the accord, a key legacy accomplishment for Obama, a Democrat.
China also helped negotiate the Iran nuclear agreement, another big piece of Obama's foreign policy that Trump has threatened to dismantle.
Neither Xi nor Obama mentioned Trump in their remarks in front of reporters.
"Mr. President, I would like to commend you for the active efforts you've made to grow this relationship," Xi said to Obama.
Obama noted that the two leaders would discuss areas of disagreement, including "the creation of a more level playing field for our businesses to compete, innovation policies, excess capacity and human rights," he said.
"I continue to believe that a constructive U.S.-China relationship benefits our two peoples and benefits the entire globe," he said.
