Hong Kong Chief Executive Carrie Lam said on Tuesday she would work closely with Beijing's top official in the Asian financial hub to get it back on "the right path" after more than six months of pro-democracy protests.

The appointment of a new head of the Chinese government's most important office in Hong Kong, Luo Huining, was unexpectedly announced over the weekend in a sign of Beijing's frustration with the latter's handling of the crisis.

The Liaison Office of the Central People's Government in the Hong Kong Special Administrative Region reports to China's State Council or Cabinet, and is the main platform for Beijing to project its influence in the city.
