University students have gathered outside Taiwan's legislative house, kicking off a scheduled 31-hour demonstration to mark the anniversary of a movement that occupied the island's parliament.

The students were preparing Sunday for a march around the compound that hundreds of student-led activists occupied for 24 days last March in what became known as the Sunflower Movement.

Last year's actions set back Taiwan's relations with China and continue to be felt. The students are demanding that officials deal cautiously with old enemy China amid public worries that Taiwan is getting too economically close to Beijing.

The activist group Black Island Nation Youth Front organized the Sunday-Monday demonstration to pressure lawmakers into approving a bill that would strengthen oversight over agreements with China.
