STORY: The Democratic congresswoman started a visit that Beijing had warned her against taking, saying it would undermine Sino-U.S. relations.
A crowd that gathered outside the Grand Hyatt Hotel, held placards that read: “I am Taiwanese. I stand for Taiwan’s independence.”
A separate group of anti-U.S. protesters also demonstrated outside the Grand Hyatt Hotel, stomping on a U.S. flag and chanted "Pelosi get-out'.
Pelosi is on a tour of Asia that includes planned visits to Singapore, Malaysia, South Korea and Japan.
China claims self-ruled Taiwan as its own, and a foreign ministry spokesman said earlier this week that any visit by Pelosi would be "a gross interference in China's internal affairs" and warned that "the Chinese People's Liberation Army will never sit idly by."
The United States said on Monday it would not be intimidated by what it called Chinese "sabre-rattling".
Most of Pelosi's planned meetings in Taiwan, including with President Tsai Ing-wen, are scheduled for Wednesday, an official familiar with her itinerary said.
