China urges relevant countries to respect China's sovereignty and Hong Kong's legal system, refrain from making irresponsible remarks on the trial of cases, and avoid intervening in Hong Kong's judiciary or interfering in China's internal affairs in any form, Lin said.

The High Court of the HKSAR on Monday morning sentenced Jimmy Lai, an instigator of anti-China riots in Hong Kong, to 20 years in prison.
