The visit is aimed at strengthening ties between the Netherlands and South Korea, while presenting a united front against North Korean aggression in the region.
After the welcoming ceremony, during which the royal couple were accompanied by Ms. Park, they proceeded inside the presidential palace where they signed the official guestbook.
Then it was to more serious matters, as King Willem-Alexander attended a brief meeting with the president on various subjects including mutual cooperation and North Korea. King Willem-Alexander praised South Korea's economic advances through recent decades, and a deal was signed that will see South Korean companies led by the Korea Atomic Energy Research Institute upgrade the nuclear reactor at Delft University of Technology and build a new nuclear research facility.
A memorandum on brain research was also signed which it is hoped will boost advances in the research of neurological and psychiatric disorders.
Later, the king and queen attended a state banquet.
