"South Korea has to think about the cost involved in keeping the deterrence at the level they would like, while the threat is clearly present", James Kim, global relations expert at the Asian Institute for Policy Studies in Seoul, told Sputnik Monday. Both were held in South Korea. The South paid 960.2 billion won for the defense cost sharing in 2018.
Trump has complained that maintaining troops in South Korea is too expensive and said in the past that he would like to bring them home.
The two countries have been in a security alliance since the 1950-53 Korean war, which ended with an armistice rather than a peace treaty - with more than 28,000 U.S. troops stationed in the South to guard against threats from Pyongyang.
He added that Washington "realizes that South Korea does a lot for our alliance and for peace and stability in this region", as quoted by Reuters.
The official Special Measures Agreement (SMA) will be officially signed by Foreign Minister Kang Kyung-wha and U.S. Ambassador to South Korea Harry Harris after Cabinet members and President Moon Jae-in approve the preliminary document.
When asked about the possibility in an interview with CBS last week, Trump said he has "no plans" to withdraw troops from the peninsula and hasn't even discussed the issue.
"If the cost of increasing the defense spending to match whatever firepower the USA forces were able to provide on the Korean Peninsula is larger than the increase [in cost-sharing], it makes no mathematical sense for South Korea to not contribute more to the cost-sharing agreement", Kim said.
Many analysts expressed concern he may make a similar gesture in his upcoming talks with Kim. President Donald Trump has said South Korea should pay more.
The probability of the Olympic bid, however, relies on the state of North Korea's nuclear and ballistic program. Situated at the epicenter of one of the world's most geopolitically volatile regions, the Korean Peninsula is of particular strategic importance to US policy and posture across East Asia. On Sunday, Seoul's Foreign Ministry said the countries signed a new deal.
About 70 per cent of South Korea's contribution covers the salaries of some 8,700 South Korean employees who provide administrative, technical and other services to the United States military.
The U.S. military also enjoys less tangible benefits, including rent-free land for its bases and an exemption that allows government-operated vehicles to use expressways toll-free.
The allies had struggled to reach a breakthrough despite 10 rounds of talks since last March, amid Mr Trump's repeated calls for a sharp increase in South Korea's contribution.
