The number of outbound travelers rose 22 percent on-year to 2.23 million in November, while 1.12 million foreign visitors came to South Korea, down 16.5 percent from a year earlier. In particular, the numbers for Chinese tourists plunged 42.1 percent to 345,000 in the same month.

China -- South Korea's largest trading partner -- has imposed restrictions on South Korean imports and banned the sale of group tour packages in retaliation for Seoul's decision to deploy an advanced US missile defense system on its soil.

South Korea and China agreed in late October to put their bilateral relations back on a cooperative track, a move that could increase the number of Chinese tourists to South Korea moving forward.

"The lifting of the travel ban will likely bring about tangible results, such as an increase in Chinese visitors, from the new year," said Roh Cung-seak, director of the monetary and financial statistics division at the BOK. "When the on-year growth of Chinese tourists returns to positive terrain, South Korea's services account will improve."

But the goods account surplus widened to $11.46 billion in November from $9.69 billion a year earlier, as rising global demand helped South Korea enjoy strong overseas sales.

The primary income account swung to a deficit of $70 million in November from a surplus of $370 million a year earlier.

Meanwhile, Asia's fourth-largest economy saw its exports rise 9.5 percent on-year to $49.62 billion in November, with imports advancing 12.7 percent to $41.99 billion. (Yonhap)
