SHANGHAI (REUTERS) - China's official English-language newspapers on Thursday (July 4) blamed meddling by Western governments for unrest in Hong Kong amid an escalating diplomatic spat between China and the United Kingdom over protests in the former British colony.

"Ideologues in Western governments never cease in their efforts to engineer unrest against governments that are not to their liking, even though their actions have caused misery and chaos in country after country in Latin America, Africa, the Middle East and Asia," the state-run China Daily said in an editorial.

"Now they are trying the same trick in China," it said.

Hundreds of protesters besieged and broke into the Hong Kong legislature on Monday after a demonstration marking the anniversary of the city's return to China in 1997 under a "one country, two systems" formula that includes freedoms not enjoyed in mainland China, including the right to protest.

That followed weeks of protests against a now-suspended extradition Bill that opponents say would undermine Hong Kong's much-cherished rule of law and give Beijing powers to prosecute activists in mainland courts, which are controlled by the Communist Party.

The China Daily accused Western forces of instigating unrest against Hong Kong's government "as a means to put pressure on the central government".

"The violent behaviour that these Western agitators are emboldening tramples on the rule of law in Hong Kong and undermines its social order," it said.

An editorial in the English edition of the Global Times, published by the Communist Party's People's Daily, criticised comments by British Foreign Secretary Jeremy Hunt and said that "the UK's diplomacy towards China will pay for his behaviour".

Mr Hunt warned on Tuesday of consequences if China did not abide by the Sino-British Joint Declaration in 1984 on the terms of the return of Hong Kong.

His comments were met by a sharp rebuke from China's ambassador to the UK, who told Britain on Wednesday to keep its hands off Hong Kong.
