SEOUL, June 28 (Reuters) - Round-up of South Korean financial markets:

** South Korean shares on Tuesday closed at their highest since mid-June, as China's pledge to roll out stimulus assuaged some worries over recession. The Korean won hit its highest in two weeks, while the benchmark bond yield fell.

** The benchmark KOSPI ended up 20.17 points, or 0.84%, at 2,422.09, extending gains for a third session.

** The Korean stock market tracked strength in Chinese markets on a still-strong policy stance to boost economic growth, said Seo Sang-young, analyst at Mirae Asset Securities.

** China's state planner officer said on Tuesday the country will roll out tools in its policy reserve in a timely way to cope with economic challenges, while its central bank affirmed accommodative monetary policy to continue.

** Meanwhile, South Korea's export growth is expected to slow sharply to a 20-month low in June, contributing to a record trade deficit, though the data will be dragged down by temporary factors, a Reuters survey showed on Tuesday.

** Among the heavyweights, technology giant Samsung Electronics jumped 1.02% and peer SK Hynix rose 0.32%, but battery maker LG Energy Solution fell 0.36%.

** Foreigners were net sellers of 37.4 billion won ($29.16 million) worth of shares on the main board, having turned net buyers a day before for the first time in seven sessions.

** The won was last quoted at 1,283.4 per dollar on the onshore settlement platform, 0.24% higher than the previous session and the highest since June 10.

** In offshore trading, the won was quoted up 0.2% at 1,283.6 per dollar, while in non-deliverable forward trading its one-month contract was quoted at 1,282.1.

** In money and debt markets, September futures on three-year treasury bonds was flat at 103.34 in late afternoon trade.

** The most liquid 3-year Korean treasury bond yield fell by 1.0 basis points to 3.560%, while the benchmark 10-year yield slipped 2.8 basis points to 3.696%.
