BEIJING, Sept. 5 (Xinhua) -- The "one country, two systems" principle should be upheld in China's Hong Kong as it has been working effectively, experts and officials have said.

Jannie Rossouw, head of the School of Economic and Business Sciences at the University of the Witwatersrand in South Africa, said there was no cause for alarm about the "one country, two systems" policy.

"I think this is a good system, it has worked for many years," he said.

He said there was clear commitment from the Chinese mainland and Hong Kong to ensure that this principle worked.

The "one country, two systems" principle is "very logical and reasonable," said Bunn Nagara, a senior fellow of Institute of Strategic and International Studies in Malaysia. "It has worked so far."

"Why disrupt it, why want to change it at all?" Nagara asked.

"We respect the constitution and the way the Chinese government manages its country," Henry Okello Oryem, Uganda's minister of state for international affairs, has told Xinhua.

"Western countries should stop lecturing other people on how they should run their own affairs," he added.

The Belarusian side has also confirmed its continued support to the one-China principle, Belarusian Foreign Ministry Spokesman Anatoly Glaz told journalists.

The diplomat also stressed that Belarus is opposed to foreign interference in China's internal affairs.

Hong Kong is a special administrative region of the People's Republic of China, Ulan Dyikanbaev, spokesman of the Kyrgyz Ministry of Foreign Affairs, said in an interview with local media on Tuesday.

"In this regard, the current events in this administrative region are an internal affair of China," he said.
