In a letter addressed to House Speaker Paul Ryan and Senate president pro tempore Orrin Hatch, Trump gave details on the missile strike on the Shayrat military airfield, launched in retaliation for an apparent chemical attack.
"The US missile strike against Syria is a clear and unforgivable aggression against a sovereign state and we strongly condemn it", EFE news cited a North Korean Foreign Ministry statement as saying.
"During the meeting the two leaders discussed this issue [of Syria]".
China and the USA agreed that Pyongyang's programmes are a serious problem, but have not seen eye-to-eye on how to respond.
The NSC also presented Trump with the possibility of assassinating North Korean Leader Kim Jong Un along with the option of infiltrating special forces into North Korea and then sabotaging key nuclear infrastructure.
General Jack Keane said: "We're rapidly and dangerously heading towards the reality that the military option is the only one left when it comes to getting North Korea to denuclearise and not weaponised ICBMs".
Speaking after the two-day summit at Trump's Mar-a-Lago resort in Florida, U.S. Secretary of State Rex Tillerson also said that Xi had agreed to increased cooperation in reining in North Korea's missile and nuclear programs - though he did not offer any new formula for cracking Pyongyang's defiant attitude.
"President Trump noted the importance of adhering to global rules and norms in the East and South China Seas and to previous statements on non-militarisation".
Senior members of the Trump administration appeared on America's Sunday morning TV news programs in a publicity offensive, including the usually media shy Tillerson. -China dialogue by putting the two presidents at the head of the forum.

Ricciardo also reveled in his earlier battle for third place with Vettel, during which the pair briefly rubbed wheels. Hamilton also observed that the conditions favored Mercedes today given the colder weather conditions in Shanghai .
In return, Xi hoped to obtain assurances from Trump on punitive tariffs and the delay of an American arms sale to Taiwan, at least until after a major Communist Party meeting later this year. However, while Washington and Beijing do not see eye-to-eye on several issues, both sides realize that economic war is not in the interest of anyone.
"This was denominated in the first instance in 100 days with hopefully way stations of accomplishment along the way". What filters from the briefings is that Mr. Trump took a measure of the complexity of the issues involved and constraints faced by China.
This raises the possibility that Trump may have used North Korea as leverage against China.
Xi would ideally have stood shoulder-to-shoulder with Trump, amid all the pomp and ostentatious kitsch of what Trump has called his "Winter White House", and impressed on the U.S. administration that China's long-sought reality of a "G2" of sorts with the United States was now a fait accompli amid Trump's supposed lurch away from the old shibboleths of USA foreign policy since the end of the second world war. "They agreed to work together in the interim to ensure a successful and results-focused visit", Spicer said.
To boost bilateral ties, Xi underlined the importance of further enhancing economic, military and law enforcement cooperation and people-to-people exchanges.
"We feel the increased presence is necessary", said a U.S. official who was not authorised to speak to the media and requested anonymity.
Another outcome of Trump's shift on Syria has been a strikingly tougher tone from his administration on Russian Federation.
Despite his tough campaign talk, Trump has so far not followed through on his threat to formally brand China a "currency manipulator", nor to hit Chinese imports with punitive tariffs. The attack was a response to the alleged chemical attack in Syria's Idlib, which Washington blames on Damascus.
