Hong Kong leader Carrie Lam left for Beijing on Saturday for her first visit to the Chinese capital since her government was handed a crushing defeat in local elections last month.
The heavy loss prompted speculation about changes to her leadership team.

She will meet Chinese President Xi Jinping on Monday, local media have said.
Hong Kong has been convulsed by daily and often violent protests for the last six months as demonstrations against a now-withdrawn extradition bill broadened into demands for greater democratic freedom.
Hundreds of thousands of people marched last Sunday to protest against what is seen as Beijing undermining freedoms guaranteed when the former British colony was handed back to China in 1997.
Many young protesters are also angry at Lam's government, charging it with failing to address social inequality issues in one of the world's most expensive cities.
This week Lam said a cabinet reshuffle was not an "immediate task" and she would focus her efforts on restoring law and order to Hong Kong.
Still, there are doubts about how long Beijing is willing to back her. Especially after pro-democracy candidates won nearly 90 percent of the seats in district elections last month.
China has condemned the unrest and blamed foreign interference.
It denies that it is meddling in Hong Kong's affairs. In an editorial this week, the official China Daily newspaper called on Hong Kong's government to uphold the rule of law.
Separately, police have arrested five teenagers in connection with the murder of a 70-year-old man last month and for rioting, the government said.
The man had been assaulted by someone with bricks and later died in hospital, the government said in a statement.- Reuters
