Officials signed a short-term agreement on Sunday to boost South Korea’s contribution toward the upkeep of U.S. troops on the peninsula, after a previous deal lapsed amid U.S. President Donald Trump’s call for the South to pay more, Reuters reported.

About 28,500 U.S. troops are stationed in South Korea, where the United States has maintained a military presence since the 1950-53 Korean War.

The new deal must still be approved by South Korea’s parliament, but it would boost its contribution to 1.03 trillion won ($890 million) from 960 billion won in 2018.

Unlike past agreements, which lasted for five years, this one is scheduled to expire in a year, potentially forcing both sides back to the bargaining table within months.
