Kim Ji-yeon zooms in on the issue.
Perhaps the most obvious impact of the trade dispute so far has been China's decision to nearly totally cut out imports of US soybeans and energy commodities such as crude oil, coal and liquefied natural gas (LNG).

Trump agreed to hold off on plans to raise tariffs January 1 on $200 billion in Chinese goods.
