Chinese President Xi Jinping on Sunday said China's determination to support multilateralism will not change, in a speech delivered via video at the opening ceremony of the 2021 Imperial Springs International Forum (ISIF).

"Multilateralism is essentially about having international affairs managed by all parties through consultation and the future of the world decided by all countries working together," he said.

"We need to pull together in solidarity and act on true multilateralism," said Xi.
