The U.S. strikes came as Trump hosted Chinese President Xi Jinping in Florida to press the leader of North Korea's sole diplomatic ally to do more to curb Pyongyang's nuclear ambitions.
The official China Daily newspaper said it was encouraging to see the two-day summit that ended on Friday "going as well as it could", after earlier "confusing signals" from Washington about how it was approaching the US-China relationship.
"President Trump said he and President Xi held in-depth discussions on the seriousness of North Korea's nuclear problem and how to respond to it, and also said he had conveyed the US position on the THAAD deployment", the statement said.
Trump, who remained at his Mar-a-Lago resort for the weekend after Xi's departure, was visiting his nearby Trump International Golf Club in West Palm Beach, Fla.at the time of the tweets.
"We have engaged in deeper understanding, and have built a trust - a preliminary working relationship and friendship", he said.
The US leader apparently did speak to Xi about another thorny issue, telling him of "the importance of protecting human rights and other values deeply held by Americans", the White House reported. And these are the kinds of progress that give us the greatest concerns.
Trump spoke publicly of progress on a range of issues in his first US-China summit - as did several of his top aides - but they provided few concrete specifics other than China's agreement to work together to narrow disagreements and find common ground for cooperation.
Asked to elaborate, he said simply: "I would just say we view sanctions as being a very important tool, whether it's North Korea or whether it's Syria".

Tillerson said Trump and Xi noted the urgency of the threat of North Korea's weapons program and that they reaffirmed their commitment to a denuclearization of the divided Korean Peninsula.
"There is a real commitment to work together to see if this can not be resolved in a peaceful way", said Tillerson.
The launch was North Korea's latest in a long series of missile and nuclear tests that have accelerated in their variation and intensity over the last two years.
At a daily news briefing Friday, Hua Chunying, a spokeswoman for the Chinese Foreign Ministry, reiterated China's support for a "political settlement" and said it was urgent to prevent any further deterioration of the situation in Syria.
North Korea has been pursuing its nuclear and missile programs at an unprecedented pace since previous year, with an aim to expand its deterrence against Washington and diversify its line-up of nuclear-equipped missiles, another expert said.
Xi also spoke in mostly positive terms but offered only broad generalities. "We have tremendous potential in our oil and gas, tourism, fish, air cargo and mineral resource industries", Walker said in a statement issued before the meeting.
At the time of the US-led invasion of Iraq in 2003, the then North Korean leader Kim Jong-Il disappeared from public view for around six weeks-and was widely believed to have gone into hiding for fear of a USA attack.
