Chinese Vice Premier Li Keqiang has arrived for a three-day visit in Hong Kong, where he is expected to announce measures to boost trading in China's currency, the yuan.

Li, widely expected to succeed Premier Wen Jiabao next year, said on his arrival in the territory Tuesday that he was bringing measures to deepen economic and trade cooperation between Hong Kong and the mainland.

He said the measures will be announced in a speech on Wednesday. China increasingly has been using Hong Kong as a laboratory for efforts to develop the yuan as an international currency.

Li will also meet with government and business leaders and tour the territory's thriving stock exchange. Local press reports said he will visit local residents in their homes to learn more about Hong Kong's development.
