SEOUL, July 21 (Reuters) - Round-up of South Korean financial markets:

** South Korean shares closed up nearly 1% on Thursday, to their highest in more than three weeks, as investors were relieved after gas supplies resumed along the biggest pipeline from Russia to Germany.

** The won strengthened, while the benchmark bond yield inched up.

** The benchmark KOSPI ended up 22.31 points, or 0.93%, at 2,409.16, closing at the highest since June 28.

** Gas deliveries through the Nord Stream 1 pipeline resumed on Thursday and gas was flowing again, easing worries about European economies struggling with energy supplies.

** Euro's gains after the report led to the dollar's weakness, which boosted inflows of foreign money to the local stock market, said Daishin Securities' analyst Lee Kyoung-min.

** Meanwhile, South Korea's exports in the first 20 days of July grew 14.5% from a year-ago period, but the country's imports increased at a much faster pace of 25.4%, bringing the trade balance to an $8.1 billion deficit.

** Investors will now eye whether the European Central Bank will raise its base rate by 25 basis points or 50 basis points during the policy meeting due later the day.

** Among heavyweights, technology giant Samsung Electronics jumped 2.15% and peer SK Hynix rose 0.49%. Battery maker LG Energy Solution also gained 1.69%.

** Of the total traded issues of 926 on the benchmark KOSPI, 563 shares advanced.

** Foreigners were net buyers of 437.9 billion won ($334.95 million) worth of shares on the main board.

** The won was last quoted at 1,307.7 per dollar on the onshore settlement platform, up 0.40%.

** In offshore trading, the won was quoted up 0.4% at 1,307.6 per dollar, while in non-deliverable forward trading its one-month contract was quoted at 1,306.8.

** In money and debt markets, September futures on three-year treasury bonds rose 0.01 point to 104.68 in late afternoon trade.
