Vow to bring ‘stability and clarity’ to the UK’s approach to Beijing on first visit by a British prime minister in eight years will be sorely tested

Keir Starmer has travelled to China with a vow to bring “stability and clarity” to the UK’s approach to Beijing after years of what he described as “inconsistency” under the Tories, but a series of issues may get in the way of his efforts to improve relations with the economic powerhouse.

One of the thorniest issues on the agenda is the case of Jimmy Lai, the jailed former media tycoon and one of Hong Kong’s most famous pro-democracy voices.

Lai is a British citizen and was found guilty by a Hong Kong court of national security offences last month that the UK sees as politically motivated. Yvette Cooper, the foreign secretary, has called for his immediate release and summoned the Chinese ambassador after his conviction.

Lai faces spending the rest of his life in prison, amid increasing fears about his physical condition. Starmer is under pressure to do what he can to secure his release. He may also raise the fate of the Uyghurs, a persecuted Muslim minority in China who have been co-opted into forced labour programmes.
