In a lengthy press conference, rebutting criticism of the Chinese government, Liu Xiaoming said the UK was at a “critical historical juncture” in its future with his country. The ambassador urged the UK to “resist pressure” from the US to condemn China.
And he rejected accusations of human rights violations against Uighur Muslims in the Xinjiang region.
The UK and China have had a number of political disputes in recent months, including over the banning of technology firm Huawei from the UK’s 5G mobile network and the new security law imposed in Hong Kong.
But Mr Liu said he hoped the governments had “enough wisdom and capabilities” to move forward from their differences “rather than allowing anti-China forces and Cold War warriors to kidnap the China-UK relationship”.
A spokesman from the Foreign Office referred the BBC to earlier statements made by Foreign Secretary Dominic Raab, saying the UK government would “work to maintain positive, constructive engagement with the Chinese government”.
