HONG KONG (REUTERS) - Hong Kong leader Carrie Lam left for Beijing on Saturday (Dec 14) for her first visit to the Chinese capital since her government was handed a crushing defeat in local elections last month, prompting speculation about changes to her leadership team.

Mrs Lam is due to discuss the political and economic situation in the China-ruled city with Beijing officials during a four-day visit. 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Kong has been convulsed by daily and often violent protests for the last six months as demonstrations against a now-withdrawn extradition Bill broadened into demands for greater democratic freedom.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 on 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 Mrs Lam's government, charging it with failing to address social inequality issues in one of the world's most expensive cities.

"Our sincerity to have dialogue with citizens has not changed," Mrs Lam said in a Facebook post on Saturday. She said her governing team would continue to pursue "different formats of dialogue to listen to citizens sincerely."

This week, Mrs 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 per cent 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.
