TAN AN TAY VILLAGE, Vietnam (Reuters) - As John Kerry's boat winds its way along the turbid waters of the Cai Nuoc river in Vietnam's Mekong Delta, the U.S. Secretary of State is taken back to the time he spent here as a commander of an American patrol boat during the Vietnam War.
But it is not only the past that brings Kerry to this remote part of the Mekong, the 12th largest river in the world. He is here to deliver a message about the growing threat of climate change and the impact it will have on the delta and the millions of people that depend on it for food, water and transportation.
