SIHANOUKVILLE, Cambodia: A US Navy warship arrived Monday in Cambodia, the first such visit in eight years to a nation that is China’s close ally in Southeast Asia. Cambodia’s government has suggested the port call reflects an upgrade in often-strained relations. The USS Savannah docked at the port of Sihanoukville on the Gulf of Thailand for a five-day visit. The Savannah, classed as a Littoral Combat Ship, carries a crew of 103.
