Now for a look at some trade numbers. Data shows the US overall trade deficit to South Korea doubled to almost 28 billion US dollars since the KORUS went into effect in 2012.

 

A break-down indicates the US registered slight trade surplus in service sector to its Asian ally, standing at 14 billion US dollars, while its commodity export lagged significantly behind. Analysts say Trump government's potential withdrawal from the deal may cause trade friction, or even trigger a trade war with South Korea. Trump has already pulled the US out of the Trans-Pacific Partnership Agreement and threatens to scrap NAFTA deal in a bid to narrow the nation's trade gap with its major trade partners.
