SHENYANG, China, April 4 (Yonhap) -- The building of a new bridge linking North Korean and Chinese border cities is well underway despite rising tensions over Pyongyang's continued military threats to strike South Korea and the United States, sources in China said Thursday.

The construction work to build the bridge over the Amnok River, also known as the Yalu River in Chinese, linking the North Korean city of Sinuiju to China's Dandong is being carried out without a hitch, while at the same time, the North is claiming that it can go to war with its enemies, according to the sources.
