Royal Navy ship shadows Chinese destroyer in English Channel

The Xian was returning from Russia's annual Navy Days in St. Petersburg. The U.K. navy says another frigate accompanied the Chinese ship up the channel three weeks ago on its way to the event.

The Westminster's commanding officer, Will Paston, says the Royal Navy "routinely monitors other country's warships through territorial waters" and the "Xian conducted herself in a safe and professional manner throughout."
