NATO chief Mark Rutte has warned the United States that China is building its navy at a dizzying pace, nearly 200 times faster than the US.
The secretary-general said that China, in particular, is building ships equipped with sophisticated weapons much faster than the US and its Western allies, which has alarmed him.
Rutte's concerns come after Chinese President Xi Jinping hosted a major military parade, attended by Russian President Vladimir Putin and North Korean dictator Kim Jong Un.
During a NATO defense summit held in Prague today, Rutte warned that the US must be much more militarily prepared.
"When it comes to shipbuilding and our navy and in particular the US Navy, I am really very concerned. China now has more ships at sea than the US, and US shipbuilding is not at a level that can reach what China is doing at the moment," Rutte said.
Nick Childs, senior researcher on naval forces and maritime security at the International Institute for Strategic Studies, which is organizing the conference, supported Rutte's concern.
"China's shipbuilding capacity is about 200 times greater than that of the United States," Childs told the BBC, adding that the American shipbuilding industry is facing high costs and numerous delays.
Although the shipbuilding market in Europe is expanding, Rutte said "we need much more if we want to collectively fill that gap."
The US Navy is a dominant naval force in the West, but it is currently spread across many fronts and has spent heavily to keep the fleet functional, well-equipped, and staffed.
In December, the Pentagon announced that the Chinese navy is the largest in the world, with a "combat force of over 370 ships and submarines, including more than 140 major surface combatants."
According to the Pentagon, most of China's fleet consists of modern ships that are capable of performing various missions, including underwater ones. China is also expected to add a third aircraft carrier to its fleet this year.
In response to the rise of Chinese military power, the US has decided to focus more on the Indo-Pacific region.
"The United States is prioritizing the prevention of war with China in the Pacific. Together, we can create a division of labor that maximizes our comparative advantages in Europe and the Pacific," Defense Secretary Pete Hegseth told European allies earlier this year.
