WASHINGTON (AFP) - South Korea's new President Moon Jae-In lobbied US leaders on Thursday (June 29) to back his policy of engagement with North Korea, as the Trump administration vowed to increase pressure on Pyongyang over its nuclear programme.
On his first overseas trip since his landslide election victory this month, Moon met with Congressional leaders ahead of a dinner with his counterpart Donald Trump.
The Trump administration has been trying to isolate the North Korean regime following a series of missile tests, including by persuading China - Pyongyang's main diplomatic ally - to help bring Kim Jong-Un into line.
But speaking on board his flight to the United States on Wednesday, Moon said Seoul and Washington should offer concessions to Pyongyang if it complies with their demands, according to multiple South Korean reports.
"Without rewarding North Korea for its bad actions, South Korea and the United States should closely consult what they may give the North in return for a nuclear freeze," he said.
"A nuclear freeze is a gate to dialogue and the exit of the dialogue is a complete nuclear dismantlement," he added.
Moon met Thursday with House Speaker Paul Ryan and top House Democrat Nancy Pelosi in an ornate room in the US Capitol, with Ryan hailing "strong" bilateral ties but only briefly addressing security issues on the Korean peninsula before reporters were ushered out.
"We have shared concerns such as the threats posed to both of our nations from North Korea," Ryan told Moon.
The South Korean president responded by saying that when it comes to humanitarian issues, "we must cross boundaries and all party lines and all try to unite together as one."
Moon also met with US senators including Majority Leader Mitch McConnell, Senate Armed Services Committee chairman John McCain and Senate Foreign Relations Committee chairman Bob Corker.
Washington, South Korea's security guarantor, has more than 28,000 troops in the country to defend it from its communist neighbor, which has been intensifying missile tests - including five since Moon's inauguration.
Pyongyang is seeking to develop nuclear-capable ballistic missiles that could reach the continental United States.
Trump has been pushing for tougher sanctions against Pyongyang to curb its nuclear ambitions and his administration has said military action was a possibility.
Washington and Seoul "share precisely the same goal, which is the complete dismantlement of North Korea's nuclear and missile programmes," a senior US administration official said.
"That is the hard challenge that we have been wresting with for a couple of decades now."
Trump seeks to heap economic and diplomatic pressure on Pyongyang "in order to change their calculus," the official said.
"Right now we see no evidence that they are seeking to reduce the threat from nuclear weapons or ballistic missile technology."
Also expected to be high on the agenda is a controversial US missile defence system that has been installed in South Korea to guard against missile threats from the North.
Though parts of the Terminal High-Altitude Area Defence (THAAD) system are already in place, Moon suspended further deployment following a furious campaign of economic sanctions and diplomatic protests by Beijing.
