Any sanctions imposed on public officers are "insults" to the rule of law, the head of Hong Kong's Law Society said on Thursday, days after the United States took action against six officials.

Its president, Roden Tong, also said in Beijing that the society would not make comments from "a political perspective", but stressed that public servants should not be interfered with when discharging their duties.

"Any sanctions targeting public officials, lawyers or even businessmen for exercising their due functions and rights in accordance with the law are an insult to the rule of law," he said.

Tong led a delegation from the society on a four-day visit to the capital, during which the group held a number of exchanges with mainland officials.

One of the meetings was with a deputy director of the Hong Kong and Macau Affairs Office, Nong Rong, he said, adding that they discussed a number of law-related topics.
