Officials from South Korea and the U.S. are meeting this week in Hawaii for talks on sharing the cost of stationing American troops in South Korea.
Before leaving for Hawaii on Tuesday, Seoul's newly-appointed top negotiator Jeong Eun-bo said he will make sure that Seoul contributes a (quote) "reasonable and equitable" amount.
These are the negotiations for the 11th such deal between the allies, the current one expiring at the end of this year.
South Korea was to pay around 890 million dollars in this year's deal, a rise of 8.2 percent.
But President Trump wants Seoul to pay potentially billions of dollars more.
