While Sir Keir Starmer and Xi Jinping continue their talks, we can bring you detail on one agreement to be signed by the prime minister later.
It covers joint UK-China law enforcement on tackling people smuggling, and is expected to include intelligence sharing on supply routes and direct engagement with Chinese manufacturers to discourage them from supplying the gangs.
It will also see the two nations agree to step up the removal of people with no right to be in the UK and crack down on Chinese gangs manufacturing synthetic opioids.
Ahead of the meetings today, Starmer said: "This deal will help us cut off the supply of boats at source – stopping crossings before lives are put at risk and restoring control to our borders.
"This is Britain back at the top table, delivering real results for the British people through our international relationships."
