Lenovo, the world’s largest PC maker, said it plans to open more manufacturing facilities outside China in a response to threatened 60% tariffs on Chinese-made goods and global geopolitical uncertainty, Chairman Yang Yuanqing said at Lenovo Tech World on October 15.

Lenovo, like most electronics manufacturers, has sited most of its plants in China, creating potential vulnerability as U.S. president-elect Donald Trump has promised to impose 60% tariffs on Chinese imports, according to Reuters.

Lenovo operates more than 30 factories in nine different markets. The company plans to open facilities in Saudi Arabia following a major investment deal with the kingdom’s Public Investment Fund, Yang said.
