One in five foreign investors in South Korea's stock markets are located in tax haven countries.
 
Ruling Democratic Party lawmaker Park Gwang-on on Thursday cited a report that tallied more than 40-thousand stockholders from 127 countries owning some 700 trillion won worth of Korean shares as of the end of August.
 
Nearly 14-thousand were U.S. nationals, while almost 38-hundred were Japanese investors.
 
The amount of stocks owned by foreigners from the 62 areas categorized as tax havens by the Korean government came to 135-point-nine trillion won, accounting for nearly 20 percent of shares held by foreign investors.

The lawmaker raised concerns regarding the growing number of stockholders from territories such as the Cayman Islands, Luxembourg, the Virgin Islands and Bermuda. He warned it could potentially increase market volatility.
