The total value of mobile transactions soared 32 percent to 5.42 trillion won, accounting for 62.1 percent of all online purchases in June.

South Koreans' direct purchases from foreign countries surged 29 percent in the second quarter of the year compared to a year earlier on rising demand for cheaper and different products.

Foreign goods worth 687 billion won were bought by South Korean shoppers via overseas Internet shopping malls during the April-June period, the data showed.

Foreign garments and fashion items were the most popular with local consumers, resulting in 241 billion won worth of purchases, followed by foodstuffs valued at 158 billion won, the data showed.

The United States was the biggest seller, accounting for 365 billion won of the sales. Europe came next with 137 billion won, followed by China with 119 billion won.

The data also showed that online sales to foreigners moved up 56 percent on-year to reach 894 billion won in the second quarter.

Chinese nationals bought goods worth 716 billion won from South Korean online shopping malls in the three-month period, followed by Japanese shoppers at 47.4 billion won. (Yonhap)
