How does investing in Vietnam help targeting the emerging ASEAN region?

Vietnam's export to the rest of ASEAN nations have reached US$ 13.6 billion in 2011 and accounted for about ten percent of the country's total GDP in 2012 (US$ 138.1 billion). With tariffs reduced on over 4,000 different products, average tariff rate in the country is ten percent. Vietnam is expecting to remove all the quantitative restrictions and non-tariff barriers it currently has. In 2013 Vietnam still maintains stable growth rates. According to the Customs Department of Vietnam, the increase in 2013 was about 28.8 percent and totalturnover between Vietnam and ASEAN reached US$ 5.3 billion over the first two month.
