Despite the recent weakening of the dollar against other currencies, Hong Kong will keep its currency pegged to the greenback and will not consider linking it to the Chinese yuan, the Hong Kong financial and treasury secretary said Wednesday.

"I think that is really a source of security to the Hong Kong financial market," K.C. Chan said.

"As far as Hong Kong is concerned, having a predictable currency is very important for the financial market. The peg to the U.S. dollar actually is serving Hong Kong very well," he said in an interview with The Japan Times.
