(CNN)A US aircraft carrier-led strike group is headed toward the Western Pacific Ocean near the Korean Peninsula, a US defense official confirmed to CNN.
The move of the Vinson strike group is in response to recent North Korean provocations, the official said.
Adm. Harry Harris, the commander of US Pacific Command, directed the USS Carl Vinson strike group to sail north to the Western Pacific after departing Singapore on Saturday, Pacific Command announced. The group had been scheduled to go to Australia.
US and South Korea conduct military drills 01:17
It is not uncommon for aircraft carriers to operate in that area, and the United States regularly deploys military assets, such as aircraft, to the region as a show of force. In fact, the Vinson was in South Korea last month for military exercises.
On April 5, North Korea launched a projectile, later identified as a Scud extended-range missile, into the sea off the Korean Peninsula. There were conflicting accounts about how far it flew. The regime also has recently conducted several missile engine tests as it works to improve its ballistic missile technology.
In September, North Korea says it successfully tested a nuclear warhead. Pyongyang claims it is pursuing nuclear weapons to defend itself from what it calls US aggression.
How much damage can North Korea's weapons do? 01:04
News of the carrier move comes just after a summit meeting between US President Trump and Chinese President Xi Jinping, where North Korea was one of the top items on the agenda.
"President Xi clearly understands, and -- and I think agrees, that the situation has intensified and has reached a certain level of threat that action has to be taken," US Secretary of State Rex Tillerson told CBS' "Face the Nation" program on Sunday.
"There's a shared view and no disagreement as to how dangerous the situation has become," Tillerson said.
Earlier this year, China called on both North Korea and the US to tone down tension on the Korean Peninsula -- North Korea by suspending its nuclear weapons program and the US by stopping military exercises with South Korea that inflame Pyongyang.
Experts: North Korea missile program advancing 02:13
Days before the summit, Trump warned that the US was prepared to act unilaterally to stop North Korea's nuclear program from advancing further should China be unwilling to use its leverage over Pyongyang.
But analysts say any unilateral military options for the US concerning North Korea posed significant problems.
While the US possesses overwhelming firepower compared to North Korea, an American strike on North Korea could expose South Korea to devastating casualties in retaliation, experts say.
Bruce Bennett, senior defense analyst at the Rand Corp. think tank, said in an email to CNN that the movement of the Vinson strike group to Korean waters is likely defensive in nature.
Sailing with the Vinson are the guided-missile destroyers USS Wayne E. Meyer and USS Michael Murphy and the guided-missile cruiser USS Lake Champlain, according to a statement from US Pacific Command.
The destroyers and the cruiser are all equipped with the Aegis missile defense system.
"If North Korea were to test some number of ballistic missiles by firing them into the East Sea/Sea of Japan, these warships would have the potential of intercepting the North Korean test missile," Bennett said.
He said they aren't carrying the weaponry needed for a strike against Pyongyang's nuclear program, something analysts consider highly unlikely.
"Because North Korea places most of its assets underground, it will be difficult for the Vinson group to do a lot of damage to North Korea on its own," he said.
Another Aegis-equipped US warship drilled with similar vessels from the South Korean and Japanese navies off the Korean Peninsula last month in what the US Navy called "a trilateral missile warning informational link exercise."

The ship is expected to replace the USS Nimitz (CVN-68), scheduled for inactivation in 2025, in the Navy fleet. The newest Kennedy will be the second carrier of that name. The first John F. Kennedy (CVA-67) was the last conventionally powered carrier. It was decommissioned in 2007.

Over 10 days in San Diego, much of the crew of each ship will transfer to the other. When completed, the Reagan will head to forward deployment in Japan, where the Washington had been. The Washington will head to Newport News, Virginia, for an overhaul.

The Nimitz-class carrier's departure was delayed for two days after marine growth clogged sea water intakes. Divers went into the 36-degree water to clean out the intakes and allow the ship to get under way. The cold water created a fog that made it seem the ship was in a cloud.
