Chinese President Xi Jinping is expected at the White House next week for his first talks there with US President Donald Trump, according to a report on the planned summit. The US military honor guard has been rehearsing and a new White House helipad is ready, the report said, even as expectations for the meeting remain low.

The agenda is shadowed by several disputes. Both countries are racing for supremacy in artificial intelligence, and the report cited warnings of an "AI apocalypse" hanging over the talks. The war with Iran also casts a long shadow, as China seeks to avoid US sanctions against countries dealing with Tehran. The report noted claims that Beijing supplied Tehran with intelligence for a strike on US troops.

Trade remains a central concern: the world's two largest economies are still seeking to mitigate the fallout from Trump's global tariffs. The threat of war over Taiwan also looms large over the summit.
