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%.
