PM's visit is eight years in the making - but what have previous relations with China looked like?
Sir Keir Starmer is expected to touch down in Beijing within the next couple of hours.
He will be the first serving UK prime minister to step foot in China in eight years, as he seeks to thaw relations between the two countries.
It follows the so-called "Golden Era" of relations between the two nations, which saw Chinese President Xi Jinping come to the UK for a state visit, and sip pints with then PM David Cameron in October 2015.
Now more than a decade ago, that visit saw the Chinese leader meet with Queen Elizabeth II, attend a state dinner, visit Manchester City FC and launch new flights between the two countries.
Three years later, in 2018, Cameron's successor, Theresa May jetted off to China for a three-day trip.
May met with Xi Jingping, discussed expanding trade links and discussed their shared commitment to protecting the environment and tackling illegal wildlife trades.
Other topics that came up on the visit included North Korea, both countries' "commitment to 'One Country, Two Systems'" in Hong Kong and "the importance of the Rules-Based International System", according to May's Number 10.
But two years later, China imposed the National Security Law on Hong Kong, which has seen pro-democracy activist and British citizen Jimmy Lai jailed, while fears about Chinese spying have soared.
Over the past eight years since May's visit, relations between China and the UK have repeatedly pivoted, but largely soured.
It should be noted that while no PM has visited for a while, Sir Keir Starmer has met with his counterpart more recently.
The two leaders met at the G20 summit in Rio de Janeiro in November 2024, where they held a bilateral meeting.
Much more recently, Chancellor Rachel Reeves held a meeting with China's vice premier and finance minister He Lifeng, while at Davos last week - as revealed by this one photo posted by the Treasury online.
Starmer will be abroad for five days in total, travelling to two Chinese cities as well as stopping off in Tokyo for a meeting with his Japanese counterpart.
