Huawei ban puts South Korea in a familiar place - caught between the U.S. and China

By Ju-min Park and Heekyong Yang

SEOUL (Reuters) - Less than a week after Huawei Technologies was blacklisted by the United States, more than a hundred South Korean politicians and business leaders toured the Chinese tech giant's headquarters and its lavish new campus outside Shenzhen.

Executives from firms such as Samsung Electronics watched demonstrations of high-speed robotics and smart city simulations powered by Huawei's next-generation 5G network equipment. The event was part of a Seoul-backed forum aimed at building tighter tech links between China and Asia's fourth-largest economy.

But the gathering was overshadowed by the U.S. decision early this month to ban American tech and telecom firms from doing business with Huawei, and a push to get companies around the world to follow suit.

The campaign against Huawei, and the broader U.S.-China trade war, have landed export-driven South Korea in a familiar bind, caught between its crucial security ally and biggest trading partner.

Key global tech companies are suspending sales of parts and software to the Chinese firm and several mobile carriers are delaying the launch of new Huawei handsets. But in South Korea, business executives and politicians said they see few alternatives to conducting business with China as normal.

For Samsung, South Korea's national tech champion, any advantages it could gain from Washington's move against Huawei would be outweighed by the pain of lost business, experts said.

Samsung could increase share at Huawei's expense in smartphones and telecom network equipment, and its stock has ticked up modestly since the U.S. ban was announced. The broader trade war could also blunt the rise of new Chinese rivals in chips and smartphone screens.

But Huawei is also one the biggest customers for Samsung's memory chips, and the South Korean firm has multiple factories in China serving a plethora of customers. Samsung Vice Chairman Yoon Boo-keun was among those who took part in the Huawei tour.

"They compete, but they are important partners too," said Min Byung-doo, a South Korean ruling Democratic Party member of parliament who was part of the tour, referring to Huawei and Samsung. He told Reuters that South Korean companies had "no simple alternative" to maintaining business relationships with Huawei.

Samsung declined to comment.

'MOMENT OF TRUTH'

South Korean government officials and tech company executives say there is plenty to worry about in the long run. China is South Korea's largest trading partner, accounting for 26.8% of the country's exports in 2018, compared with 12% for the United States.
