Shi Zhanxiong, a political advisor from Hong Kong said he would focus on ways to keep the city's economic traits and competitive power as cities in south China are catching up with Hong Kong.

Shi was among a 50-member delegation from Hong Kong who arrived in Beijing Tuesday afternoon to attend the annual session of the National Committee of the Chinese People's Political Consultative Conference (CPPCC), which would open on Wednesday.

Lu Yaodong, vice chairman of the K.Wah Group said he was interested in what plans the government would lay out to support the domestic powerful brands in the service sector amid the nation's drive to stimulate domestic demand.
