Taiwan's parliament approved Wednesday evening an upgraded infrastructure stimulus plan worth T$420 billion ($12.6 billion) to be implemented over the next four years to revive the island's sluggish economy, which is heavily dependent on exports.

The original plan, which was amended after opposition inputs, had included rail construction, digital infrastructure, green energy, water supply.

The updated plan includes three new projects on senior citizens nursing care, food security and talent and employment promotion.

The plan will even out a development divide between the north and the south, and help Taiwan meet global challenges, such as climate change, Taiwan's Prime Minister Lin Chuan said.

The proposed budget for the project will be discussed next week in the parliament.

The opposition Kuomintang Party, which ruled from 1949 to 2000 and from 2008 to 2016, had strongly opposed the original plan alleging many of the expenses, especially those on railway construction, were politically motivated.
