Areas surrounding the Presidential Office were packed with supporters of the pro-independence Taiwan Solidarity Union, who chanted slogans on national identity, The South China Morning Post reported Monday.
Calling for the island's official name, the Republic of China, to be changed to Taiwan, they marched from the Chiang Kai-shek Memorial Hall to the boulevard in front of the Presidential Office.
Small clashes were reported as TSU supporters passed the headquarters of the opposition Kuomintang, which held a big rally nearby.
