Hong Kong (CNN) A satellite image obtained by CNN shows China has deployed at least four J-10 fighter jets to the contested Woody Island in the South China Sea, the first known deployment of fighter jets there since 2017.

The image was taken Wednesday and represents the first time J-10s have been seen on Woody or any Chinese-controlled islands in the South China Sea, according to ImageSat International , which supplied the image to CNN.

The deployment comes as tensions remain high in the South China Sea and Chinese President Xi Jinping prepares to meet United States President Donald Trump at the G-20 summit in Japan next week.
