BEIJING, June 28 -- A mainland spokesperson Wednesday stressed opposition to any activities that undermine prosperity and stability in Hong Kong Special Administrative Region (HKSAR).

Ma Xiaoguang, spokesperson for the State Council Taiwan Affairs Office, made the remarks in response to a question about comments regarding Hong Kong's implementation of the "one country, two systems," which were made by a Taiwan official.

"We resolutely oppose any interference with Hong Kong's implementation of the 'one country, two systems' principle," said Ma, at a press conference.

During the last 20 years, "one country, two systems" has proven not only to be the best solution, but the best institutional arrangement for long-term prosperity and stability since its return, Ma said.

In response to another question on the relationship between Hong Kong and Taiwan in the last 20 years, Ma said that the HKSAR government had adhered to the Basic Law and the central government's basic principle and policy on Taiwan.

The HKSAR government has adopted favorable policies and taken measures conducive to people-to-people communication between Hong Kong and Taiwan, and properly handled affairs related to Taiwan within its autonomous region, Ma said.

Under the central government's approval, guidance or authorization, the HKSAR has properly dealt with affairs involving national sovereignty and cross-Strait relations and boosted people-to-people and financial exchanges between the two sides, Ma said.
