Let turn to the first visit to Seoul by a head of state from an ASEAN member country.
Philippines President Rodrigo Duterte spent Monday afternoon at South Korea's top office, with a summit with President Moon Jae-in.
Our Cheongwadae correspondent Hwang Hojun has more on what was discussed. "May our relations remain strong and continue to thrive for the benefit of both the Korean and Filipino peoples."
After writing that message in the Cheong Wa Dae guestbook, Philippine President Rodrigo Duterte and his South Korean counterpart held a summit meeting together on Monday.
President Duterte is the first head of state from an ASEAN member country to visit Seoul since President Moon took office.
But this was actually the second time the current Presidents of South Korea and the Philippines have met.
The first was on the sidelines of the ASEAN+3 summit and the East Asian Summit, last November.
In Monday's meeting, the two leaders highly evaluated the 69 years of diplomatic relations between their countries.

"Korea and the Philippines have made remarkable achievements in all areas, including politics, economy, culture, and human exchanges over the past 70 years based on our strong friendship established through the Korean War."

President Moon noted that South Korea is the Philippines' fifth-largest trading partner and that human exchanges between the two countries have risen steadily.
And to further promote such partnerships, the two leaders agreed to designate 2019 a visit South Korea-Philippines year,... which will mark the 70th anniversary of the two countries establishing diplomatic ties.
According to a Blue House press release, the South Korean President also expressed his gratitude for the Philippines' support for the Moon administration's efforts to peacefully resolve of the North Korea nuclear issue... as well as for the recent improvements in inter-Korean relations.
The two leaders pledged their commitment to the denuclearization and establishment of peace on the Korean Peninsula.
Also discussed during their meeting was economic cooperation between Seoul and Manila.
President Duterte said that President Moon's "New Southern Policy," which seeks to expand South Korea's diplomatic relations and economic cooperation with ASEAN nations,... will help the Philippines achieve its own economic goal.
Known as the "Ambisyon Natin 2040," President Duterte's own long-term policy is aimed at transforming the Philippines into a mid-to-high-income nation by the year 2040 by creating a trustworthy, poverty-free middle-class society.
Soon after their summit, Presidents Moon and Duterte signed an M-O-U pledging cooperation between their two countries in areas including transportation, trade, and renewable energy, which was then followed by a joint press conference.
And to honor the visiting Philippine President, a dinner banquet and cultural performances were hosted by the South Korean president.
