South Korean President Moon Jae-in arrived in Washington on Wednesday for talks with President Donald Trump. 

The presidential office in Seoul said the goal of the meeting is to build trust and friendship. 

A key topic is likely to be DPRK's ongoing nuclear and missile programs. 

While both sides have different opinions on how the situation should be addressed, both agree that Pyongyang must put a stop to its nuclear ambitions. 

Moon’s decision to suspend deployment of the THAAD anti-missile system and reduce the scale of joint military drills have also annoyed Washington.
