The worsening pandemic in China, which is Taiwan's largest trade partner, has also "disrupted consumption and manufacturing activities", it said.

Taiwan, despite its size, is one of the world's most important economies thanks to its outsized role in producing high-tech equipment, particularly state-of-the-art semiconductors, an industry that it dominates.

The island weathered the initial coronavirus pandemic well, becoming one of the few economies to record growth in 2020.

In 2021 it saw an explosion of orders as the world began reopening after months of pandemic shutdowns. Demand for semiconductors was enormous and Taiwan's foundries could barely keep up.

The following year saw strong growth initially but demand cratered in the last quarter.

The island's exports fell 8.63 per cent in the last three months of 2022 from the same period last year, the figures released on Wednesday showed.

Exports to China and Hong Kong dropped even further by 15.6 per cent, the government said.

Full-year GDP growth for 2022 was estimated at 2.43 per cent for 2022, lower than the previous projection of 3.06 per cent, it said.

"This slow growth factor is here to stay, at least in the first half of 2023. Even mainland China's reopening could not boost semiconductor demand a lot," Iris Pang, ING's chief economist for Greater China, told AFP.
