Vietnam is set to remain the fastest-growing major country in Southeast Asia this year, with consumers boosting spending as a robust economy lifts household incomes. The latest quarterly survey from FT Confidential Research shows Vietnamese consumer sentiment at a three-year high, but continued economic success depends on the government successfully managing its partial withdrawal from the economy and its relationship with a newly assertive China.

Our survey of 5,000 consumers across Thailand, Indonesia, the Philippines, Malaysia and Vietnam found young Vietnamese among the most optimistic about their country's economic outlook, propelling the FTCR Vietnam Economic Sentiment Index to its highest level since the start of 2015.
