HONG KONG - "One country, two systems" policy is the key framework that makes Hong Kong "special" and competitive, Kurt Tong, US Consul General to Hong Kong and Macau said here on Thursday.

"US's view on this is crystal clear," he said, "The United States recognize that Hong Kong is part of China. We also very much value the high degree of autonomy that Hong Kong enjoys under the 'one country, two systems' policy," Tong addressed a luncheon held by the American Chamber of Commerce.

Tong said the construct of "one country, two systems" has been highly successful in protecting Hong Kong's open society and institutions.

Hong Kong's specialness not only lie in the geography, economy and culture sectors, while the most important factor is the strong rule of law, transparency and openness, which cerate the basis for business and trade to succeed, he added.

He said the relationship between the United States and China's Hong Kong has been quite "successful" in areas such as finance, trade, investment, education and exchange programs, and the United States aims to streamline the visa appointment process in future to attract more students and visitors.

It was the first public speech Tong has made after he assumed the duties on Aug 26 this year.

Prior to his service in Hong Kong, Tong was the Principal Deputy Assistant Secretary for the Bureau of Economic and Business Affairs at the Department of State.
