BEIJING, Dec. 15 (Xinhua) -- China deplores and firmly opposes certain country blatantly making false accusations against Hong Kong's judicial affairs, Chinese foreign ministry spokesperson Guo Jiakun said on Monday.

Guo made the remarks at a regular news briefing when asked to comment on Jimmy Lai's verdict by the High Court of the Hong Kong Special Administrative Region, which was criticized by Britain and some NGOs.

Lai, an instigator of anti-China riots in Hong Kong, was found guilty on Monday on two charges of conspiring to collude with external forces and a charge of conspiracy to publish seditious materials.

"Hong Kong upholds the rule of law. The central government firmly supports Hong Kong in safeguarding national security and punishing crimes that endanger national security in accordance with the law," Guo said.

Judicial authorities in Hong Kong fulfill their duties, safeguard the authority of the law and defend national security in accordance with the law, Guo said, adding that this is justified, legitimate, lawful and beyond reproach.

"The relevant judicial case is purely Hong Kong's internal affair. We urge relevant country to respect China's sovereignty and the rule of law in Hong Kong, and refrain from making irresponsible remarks on the trial of judicial cases in Hong Kong or meddling in Hong Kong's judicial affairs and interfering in China's internal affairs in any form," he said. ■
