BEIJING — US Defense Secretary Robert Gates said China's rapidly developing defense capabilities are worrisome to the United States on Sunday.
China has made strides in building a new stealth fighter jet and Washington is also concerned about a new ballistic missile that could theoretically explode a US aircraft carrier nearly 2,000 miles (3,200 kilometers) out to sea. China has also apparently beaten US estimates to develop that weapon.
"They clearly have potential to put some of our capabilities at risk," Gates told reporters traveling with him to Asia. "We have to pay attention to them, we have to respond appropriately with our own programs."
