The country received 1.67 million international visitors in July alone, up 6.6 per cent year on year, according to the General Statistics Office (GSO).
The Vietnam National Authority of Tourism (VNAT) said sustained double-digit growth reflected the country's growing appeal, supported by easier visa policies, expanded air links and tourism promotion despite global uncertainties.
China remained Vietnam's largest source market with about 3.1 million visitors, accounting for 22.2 per cent of total arrivals, followed by South Korea with 2.4 million.
Russia ranked third with 864,000 visitors, up 174 per cent from a year earlier, becoming Vietnam's largest European source market. VNAT attributed the growth to restored direct flights, more frequent services and stronger demand for beach holidays.
Europe remained the fastest-growing region, with arrivals rising 53.4 per cent year on year. Poland, the Czech Republic, Sweden and Switzerland also posted strong growth, benefiting from Vietnam's visa waiver policy.
Among Asian markets, the Philippines recorded the strongest growth at 63.6 per cent, followed by India, Cambodia, Singapore, Indonesia and Malaysia.
Long-haul markets also expanded steadily, with arrivals from the United States up 18.3 per cent, Canada 25.1 per cent, Australia 22.5 per cent and New Zealand 22.4 per cent.
