His comments come after he pressed South Korean President Moon Jae-in Thursday to be clear-eyed about opening talks with North Korea around the Olympic games.
It was an extremely busy day for the South Korean President on Friday as he held separate one-on-ones with world leaders.

As she delivered the letter, Kim verbally stated her brother's "willingness to improve South-North Korea relations" and said he was willing to meet Moon "at the earliest date possible", the spokesman said.
The discussions from Saturday's meeting weren't immediately released.
Those people will be unhappy if the matter re-emerges following the meeting between Abe and Moon, though it is thought that Moon would likely express his views on the matter.
Moon has already put a summit offer on the table.
North Korea sent nearly 500 representatives, including athletes and 230 people state-sanctioned cheering team to PyeongChang to join with South Korea's delegates in an attempt for the rival nations to revive diplomatic communications.
"This is the strongest action yet by North Korea to drive a wedge between the South and the United States", said Kim Sung-han, a former South Korean vice foreign minister and now a professor at Korea University in Seoul.
The parade, marking the 70th anniversary of the founding of the North Korean army, was attended by leader Kim Jong Un and other senior officials.
It was the first time a member of the ruling family ever visited the presidential palace, called the Blue House.
At a glittering but sub-zero ceremony, South and North Korea brought the crowd to its feet as they entered behind the blue-and-white Korean unification flag.South and North Korea last marched together at the 2006 Winter Olympics in Turin.
An official travelling with Japanese Prime Minister Shinzo Abe in Pyeongchang told reporters the Japanese government believed sanctions were "starting to bite", citing recent instances of ship-to-ship transfers at sea.
It was not immediately known what they said, but all of them were smiling. USA officials have grown increasingly dire in their warnings about the North's march toward developing an operational nuclear-tipped ballistic missile capable of reaching the continental U.S. The North also a year ago conducted its sixth and most powerful nuclear test to date.
Pence is in South Korea, where he is leading the US delegation to the games' opening ceremonies.
Still, Kazianis said, North Korea "wanted to make a point" to the United States that it will not give up its weapons programs.
But the pinnacle of Pence's messaging was at the opening ceremony itself, where his personal guest was the father of American student Otto Warmbier, who died past year after being returned home in a coma after his 17-month detention in North Korea. It was built in the 1960s as a luxury facility for US troops stationed in the South.
The North Korean pair were seated nearly directly behind the Pences, but there was no interaction between them.
The vice-president's deliberate snub to the North Koreans - and, by extension, the host country - highlighted the deep divisions between Washington and Seoul on how to deal with Pyongyang.
The North has sent almost 500 people to the Pyeongchang Games, including officials, athletes, artists and also a 230-member state-trained cheering group after the Koreas agreed to a series of conciliatory gestures for the games.
