Hong Kong police fired tear gas in late-night street clashes with anti-government protesters, ahead of a potentially pivotal meeting between Hong Kong's leader and China's president in Beijing on Monday.
Hong Kong Chief Executive Carrie Lam, in the Chinese capital for a regular duty visit, is set to meet Xi Jinping amid speculation the visit could yield fresh directives on the city's political crisis, including a possible cabinet reshuffle.
Hong Kong has been embroiled in its worst political crisis in decades since June with anti-government protests posing a populist challenge to China's Xi. The unrest has also complicated ties between China and the United States at a time of heightened tensions, including over trade.
