German Chancellor Angela Merkel and Chinese Premier Li Keqiang announced Thursday that they would strengthen their cooperation to promote peace and stability in the world "at a time of global uncertainties".
Li used Thursday's meeting with Merkel to reaffirm China's commitment to "steadfastly" implement the Paris climate agreement, even if the U.S. pulls out.
Juncker said: "If the US president pulls out of the Paris agreement, and he will in the next days or hours, then it is Europe's duty to say that that is not how it works".
He added: "Fighting climate change is a global consensus, it's not invented by China. and we realize that this is a global consensus agreement and that as a big developing nation we should shoulder our worldwide responsibility".
"There's a lot we can offer each other", said vice foreign minister Wang Chao in the run-up to the European tour by Li.
While not mentioning the U.S.by name, Chinese Foreign Ministry spokeswoman Hua Chunying tells reporters climate change is a "global challenge" that no country can ignore.

A witness told them Sterling sent them a Facebook message stating he was threatening to shoot officers and was heavily armed. However, this did not seem to occur on Thursday, with the armed man slipping through into the convention while fully armed.
China's number two official was received with military honours at Chancellor Angela Merkel's office, becoming the second leader of a rising Asian giant to visit in as many days after India's Narendra Modi.
Five Nordic countries have written a last-minute letter to President Donald Trump urging him to "make the right decision" and keep America signed onto the Paris climate accord. Mr Johnson told Sky News that Britain still wants the USA to take the lead in fighting climate change and called on individual U.S. states to keep making progress on that front.
It commits them to cutting back on fossil fuels, developing more green technology and helping raise billions of pounds to help poorer countries cut emissions.
"The Americans can't just exit this climate protection treaty", EU Commission President Jean-Claude Juncker, who is to be among the officials meeting Li, said in a speech in Berlin on Wednesday.
Trump claimed before taking office that climate change was a "hoax" created by China to hurt the US economy, an assertion that stands in defiance of broad scientific consensus.
She said Beijing will uphold the outcome of the Paris Agreement and its implementation.
However, thorny issues remain between the two exporting nations, with Merkel insisting that China opens up its markets and that German firms operating there should have a level playing field.
