Tearing down signboards and chanting anti-government slogans, protesters unexpectedly broke through security barriers and took over the parliament's main chamber late yesterday, in the first such occupation of the building in the island's history.
The protesters, mostly young students, have barricaded the entrance with ceiling-high piles of armchairs, blocking hundreds of policemen who attempted vigorously early today to push their way in to end the occupation.
"The trade pact must not be approved without careful deliberation and scrutiny in parliament," a student leader said.
The pact - designed to further open up trade between Taiwan and China, which split 65 years ago after a civil war - passed the first hurdle in parliament Monday after it was approved by a joint committee despite opposition concerns that it could hurt small service companies and damage the Taiwanese economy.
The China-sceptic DPP has pledged to mobilise supporters when parliament holds a full session on Friday for a second review of the bill.
The pact is one of the follow-up agreements to the sweeping Economic Cooperation Framework Agreement signed in 2010 to reduce trade barriers.
Under the deal, China will open 80 service sectors to Taiwanese companies, while Taiwan will allow Chinese investment in 64 sectors.
But China still considers Taiwan as part of its territory awaiting reunification - by force if necessary.
