North Korea considers Syria to be one of its few allies.
On Sunday, North Korean officials called the USA action in Syria "absolutely unpardonable", and claimed the strike proved that its own nuclear weapons were justified to protect the country against Washington's "evermore reckless moves for a war".
North Korea's state-run news agency said a foreign ministry spokesman called the strike "absolutely unpardonable as it was an undisguised act of aggression against a sovereign state".
According to NBC News, both scenarios were part of a review of North Korea policy prepared ahead of Trump's meeting with Chinese President Xi Jinping this week.
Reuters reported the carrier will move near the Korean peninsula, citing a US official it did not identify.
Following the airstrikes on Friday, the U.S. has warned the Assad regime it is prepared to take further action in Syria if necessary. The North has long claimed that the U.S.is preparing some kind of assault against it and justifies its nuclear weapons as defensive in nature.
The response by North Korea's foreign ministry, carried by the official KCNA news agency, was the first since United States warships in the Mediterranean Sea launched dozens of missiles at a Syrian air base which the Pentagon says was involved in a chemical weapons attack earlier in the week.
North Korea has shown signs of preparing for a test of an intercontinental ballistic missile, which could potentially deliver a nuclear warhead to the US mainland, and a sixth nuclear test.
Since then, North Korea has further ramped up its tests and rhetoric, emphasising a consistent message: To create a nuclear device small enough to mount on an intercontinental ballistic missile (ICBM), and fire it at the United States.
Tensions on the peninsula seem set to climb, whether USA action in Syria heightens fiery exchanges between Washington and Pyongyang or China decides to step in.
The two Koreas are technically in conflict after the 1950-53 Korean war ended with an armistice rather than a peace treaty, and relations between them have plunged in recent months.
"Swaggering as a superpower, the USA has been picking only on countries without nuclear weapons and the Trump administration is no exception", the foreign ministry spokesman said, according to KCNA.
Some experts think North Korea has tried to make sure the two world leaders are aware Pyongyang has a bargaining chip in any forthcoming moves to clam down on its weapons programmes.
