Beijing, May 4 (IANS): China on Thursday slammed a hearing of a US commission over issues concerning Hong Kong.

"The hearing is an overt interference in China's internal affairs. China is strongly dissatisfied and firmly opposed to it," said Foreign Ministry spokesperson Geng Shuang.

The US Congressional-Executive Commission on China (CECC) hearing, held on Wednesday, was titled "Will the Hong Kong Model Survive? : An Assessment 20 years After the Handover", Xinhua news agency reported.

Geng said that over the past two decades, the policies of "one country, two systems", "Hong Kong people governing Hong Kong", and a high degree of autonomy had been implemented in effect.

"This is a fact accepted by anyone without prejudice," he said.

The spokesperson said the CECC has always been biased on issues regarding China.

"The hearing, which said the 'one country, two systems' model met encroachments, and press freedom and judicial independence were threatened, disregard the fact and has ulterior motives," Geng said.

Hong Kong is a special administrative region of China, and its affairs are purely China's internal affairs, the spokesperson added.
