DANDONG, China, June 13 (Yonhap) -- More than 100 Chinese soldiers took part in a river-crossing exercise on its Yalu River border with North Korea Tuesday, renewing speculation the Chinese military is preparing to defend against any influx of North Korean refugees following possible regime collapse in Pyongyang.
Uniformed soldiers wearing orange life vests could be seen building and rebuilding about a dozen pontoon bridges at various points along the Yalu River, which separates China and North Korea. Each bridge stretched 20 to 30 meters, made up of six or seven sections connected to each other.
