Hong Kong police fired tear gas at protesters who built barricades, started blazes and paralyzed traffic in the territory's prime business area yesterday after a peaceful march to the U.S. consulate in a bid to ramp up worldwide pressure on Beijing.
US Defence Secretary Mark Esper on Saturday urged the Chinese government to exercise restraint in Hong Kong.
Lam last week said she would formally withdraw a bill allowing extraditions to the mainland, which triggered the unrest in early June. Wong, a leader of Hong Kong's 2014 pro-democracy protest movement, was among several people detained last month and was charged with inciting people to join a protest in June.
Beijing's ire has also been directed towards the United Kingdom, which has called on Hong Kong to respect citizens' rights under the "one country, two systems" agreement that preceded the handover of the territory from British rule.
It blasted the crowds who sang "The Star-Spangled Banner" as they marched to the US Consulate on Sunday as the "illegal behavior of radical protesters" and cautioned that "foreign legislatures should not interfere in any form in the internal affairs" of Hong Kong.
In an updated travel advisory for Hong Kong on Friday, the US State Department warned that citizens and consular employees had become targets of a propaganda blitz by China "falsely accusing the United States of fomenting unrest". According to reports Monday, Wong was arrested on Sunday just before his planned trip to Germany and the U.S.to give interviews and speeches.
"Are you insane?" was hung from the overpass, and protesters repeatedly chanted slogans such as "USA", and "Fight for freedom, stand with Hong Kong".
Police public relations chief Tse Chun-chung said Monday that police are investigating the case.
"We are pleading with the U.S.to pass the act to sanction Hong Kong and Chinese authorities for gross violations of human rights", said Chen.
"We can't leave because there are riot police", said protesters Oscar, 20, in Causeway Bay.
"We want to use the U.S.to push China to do what they promised over 20 years ago", said the man, who spoke on the condition of anonymity. Any use of China's military threatens to undermine the autonomy that underpins its special trading status with the USA - a policy crucial to its economy.
Fitch also stated that it had a negative outlook on Hong Kong due to potential for renewed social unrest which could "further undermine confidence in public institutions, and tarnish perceptions of [the city's] governance, institutions, political stability, and business environment".
Demonstrations have at times paralysed parts of the city, a major Asian financial hub, amid running street battles between protesters and police who have responded with tear gas, pepper spray and water cannon.
The protesters' other demands include the retraction of the word "riot" to describe demonstrations, the release of all those arrested and the right for Hong Kong people to choose their own leaders.
When granting bail, the court ruled at that time that although Wong has to abide by a curfew and can not leave Hong Kong, he will be allowed to continue with pre-arranged trips overseas, including one to Germany this week where he is due to give a speech.
In a statement made on Twitter through his legal representative, Wong said that he believed an error was made on his bail certificate from an earlier arrest and that he expected to be released after a hearing on Monday.
