A spokesman for the office criticized the European Union Delegation to Hong Kong and the consulates of the UK, the US and other countries in Hong Kong, saying some external forces were bucking the tide and stubbornly stirring up issues that have already been resolved.
“Some staff at foreign consulates in Hong Kong have ignored basic consular ethics and codes of conduct, and are using outdated tactics of ideological infiltration and peaceful evolution to stage political drama under the pretext of ‘human rights’,” the office said in a statement on Tuesday night.

The spokesman said these actions were intended to create conflict, incite hostility and maliciously tarnish China’s image.
“Their malicious intent to destabilize Hong Kong and contain China is clearly evident,” he said.
China’s Hong Kong Office of the Ministry of Foreign Affairs urged the consulate to abide by basic norms in international relations and stop interfering in Hong Kong and China affairs.
On Tuesday, the British, US, Canadian and Australian consulates in Hong Kong posted on social media to mark the anniversary of the crackdown amid uncertainty about any public commemorations.
Electric candles were also seen lining the windows of the US consulate and EU offices.
Diplomats including European Union Deputy Secretary-General Matthias Kaufmann, German Consul General Stefan Bredour and Dutch Consul General Arjen van den Bergh were among those in Victoria Park, which had also previously hosted a candlelight vigil to mark the anniversary.
The three did not answer questions from reporters, but were seen walking together in the park surrounded by police and reporters at around 7:30 pm during the rally.

The three were wearing business suits, and the EU delegation was also seen browsing a food carnival organised by pro-Beijing groups at a football field in the park.
Also at the scene were French Special Envoy Christie de Lourouet, Belgian diplomat David Lomastro and Japanese Consul General Kenichi Okada.
In response, the Hong Kong government said some rights and freedoms may be restricted in accordance with the law to safeguard national security, public safety and order.
“If anyone breaks the law, law enforcement agencies will deal with them in accordance with the law,” the spokesman said, warning that forces were still trying to undermine social stability and threaten public safety in Hong Kong.
