U.S. President Donald Trump is expected to stress the importance of the Seoul-Washington alliance, international cooperation for pressure against Pyongyang and a swift amendment of the bilateral free trade agreement when he visits South Korea next week. 

A senior U.S. government official said Tuesday in a telephone briefing on Trump's Asia trip that the president will ask the international community to participate in maximum pressure against the North's threats during his speech at Seoul's National Assembly. 

The official added that Trump won't visit the heavily fortified Demilitarized Zone(DMZ) when he travels to South Korea as there won't be enough time to accommodate the trip. He will instead visit the U.S. military base Camp Humphreys on Tuesday, the first day of his two-day trip to the nation.
 
The official said the White House felt Camp Humphreys would make more sense in terms of the president's message by drawing attention to "South Korea's role in sharing the burden of supporting this critical alliance."
 
Trump will also hold summit talks with President Moon Jae-in and attend a state dinner next Tuesday. The U.S. president will give a speech at South Korea's National Assembly on Wednesday before flying to Beijing.
