Izumi Kobayashi, director at Japan's Mizuho Financial, Omron and ANA, said on Tuesday that companies should not overreact to U.S. president-elect Donald Trump's threats of imposing tariffs on Chinese goods.

At an interview at the Reuters Next conference in New York, she said that it would be difficult to withdraw from China given its mammoth size.

Kobayashi said that industrial conglomerate Omron has not yet taken any action to prepare for potential sanctions the incoming Trump administration may impose, but there are some ongoing discussions about it.
