US President Donald Trump has congratulated Chinese leader Xi Jinping on his "extraordinary elevation" after this week's Communist Party congress.
Mr Trump also praised Mr Xi in a TV interview in the US, and said "some might call him king of China".
Mr Xi cemented his hold on China when he had a second five-year term confirmed, with no clear successor, at the congress.
His name and doctrine have been written into the party's constitution.
The two leaders are due to hold talks at a state visit to China next month, having met at the G20 summit in July.
