The Biden administration wants to signal that the US continues to maintain its commitment, protecting its interests in the Asia-Pacific and China should not underestimate them.

Just three days after US President Joe Biden took office, the Chinese Air Force on January 23 dispatched a powerful lineup of 8 H-6K bombers and many fighter escort to overwhelm Taiwan.

Shortly thereafter, the US Navy immediately announced the USS Theodore Roosevelt aircraft carrier group to enter the South China Sea to "carry out routine operations".

Sharing with VnExpress, Carl Thayer, professor emeritus at the University of New South Wales in Australia, said that based on the statements of the "regular operation" of the US, can see the deployment of the carrier battle group.

"Apparently senior officials in the Pentagon, Indo-Pacific Command and Seventh Fleet allowed the operation to be carried out three days after Biden took office because it understood that it was in line with policy.

China has always viewed Taiwan as part of a territory awaiting reunification.

On January 24, China continued to send 15 military aircraft into the Air Defense Identification Area (ADIZ) of Taiwan.

"The deployment of the carrier strike group is a show of force aimed at sending a message to China and reassuring Taiwan," said Thayer.

New US Secretary of State Anthony Blinken said on January 19 at a Senate hearing that China poses the most important challenge to the US and he supports more involvement in the Taiwan issue.

Hsiao Bi-khim, Taiwan's diplomatic representative in Washington, was invited to attend Joe Biden's January 20 inauguration.

On January 23, in response to Chinese aircraft entering Taiwan's ADIZ, US State Department spokesman stated: "We urge Beijing to stop applying military, diplomatic and economic pressure on

A day later, the new US Defense Secretary Lloyd Austin phoned his Japanese counterpart Nobuo Kishi, reaffirming that Article 5 of the US-Japan Defense Treaty included the disputed group of islands known as Senkaku by Japan.

"These actions of the Biden administration send a clear signal to Beijing that the US will not be distracted by pressing domestic problems. The US has the political will and capacity to respond to provocative actions.

Dr. Collin Koh Swee Lean, an expert from the Institute for Strategic and Defense Studies at the S. Rajaratnam School of International Studies, Singapore (RSIS), commented that the Biden government from the very beginning showed its commitment to security.

"Recent military moves signal to China that the United States under the Biden administration continues to see Beijing as a challenge, even though they may be able to deal with it in different ways than Trump.

Vice Admiral Yoji Koda, a former commander of the Japan Self-Defense Force's Self-Defense Fleet, assessed that US Indo-Pacific strategy and policy would not change under the Biden administration.

The US armed forces are capable of defeating the Chinese military and that capacity will not decline in the future, despite many saying that "America is weakening".

The deployment of the aircraft carrier Theodore Roosevelt to the South China Sea demonstrates the determination of the US in realizing the above policies and strategies.

The former commander said that the US has a strong will to protect partners and allies such as Japan, Australia, and South Korea, including unofficial allies like Taiwan Island.

"The US message is that under the Biden administration, the United States will continue to uphold its commitments and defend its interests," said Bonnie Glaser, an expert at the Center for Strategic and International Studies (CSIS).

"The United States remains determined to maintain its leading position in the region. The Biden administration sends a strong message that it does not intend to let its leadership in the Indo-Pacific easily fall into the hands.
