A barge is seen attached to the stern of the US aircraft carrier USS Carl Vinson anchored off the coast in Danang (background R), Vietnam on March 5, 2018. The USS Carl Vinson (CVN-70) arrived in Vietnam March 5 for the first time since the end of the war, as the former foes bolster military ties in the face of Beijing’s build-up in the disputed South China Sea. The carrier will make a four-day port call for a highly symbolic trip that will include a visit to a centre for victims of Agent Orange, the toxic defoliant sprayed over large swathes of land by the US during the Vietnam war.
