Top-level meeting shows China - and Xi - still a priority for Biden

Jake Sullivan has arrived on his first visit to China as US national security adviser. He will hold talks with Foreign Minister Wang Yi as the two countries try to stabilise relations.

Mr Sullivan and Mr Wang have met four times over 16 months in Vienna, Malta, Washington and Bangkok. Their last meeting in January was shortly after a high-stakes summit between Presidents Xi Jinping and Joe Biden that sought to reset frosty ties.

This week's talks - scheduled for Tuesday and Wednesday - signal that China is still a priority for the Biden administration, even as the retiring president enters his final months in office.
