SEOUL, Sept 10 (Reuters) - Round-up of South Korean financial markets: ** South Korean shares ended higher on Friday as tech heavyweights rebounded and news of a call between the leaders of the world’s two biggest economies offered some relief to investors. The won and the benchmark bond yield also rose. ** The KOSPI closed up 11.06 points, or 0.36%, at 3,125.76, snapping a three-day losing streak. The index, however, slid 2.35% on a weekly basis, reversing two straight weeks of gains. ** Among the heavyweights, chipmaker SK Hynix rose 1.94%, while web portal operator Naver and mobile messenger app operator Kakao jumped 2.76% and 1.17%, respectively. ** U.S. President Joe Biden and Chinese leader Xi Jinping spoke for 90 minutes in their first talks in seven months on Thursday, discussing the need to avoid letting competition between the world’s two largest economies veer into conflict. ** “A rebound in Naver and Kakao and hopes for normalisation of relations between the U.S. and China helped lift KOSPI up,” said Kim Seok-hwan, an analyst at Mirae Asset Securities. ** Foreigners were net sellers of 520.2 billion won ($445.14 million) worth of shares on the main board. ** The won ended at 1,169.1 per dollar on the onshore settlement platform, nearly unchanged from the previous close. ** In offshore trading, the won was quoted at 1,168.7 per dollar, up 0.1% from the previous day, while in non-deliverable forward trading its one-month contract was quoted at 1,169.3. ** In money and debt markets, September futures on three-year treasury bonds fell 0.02 point to 110.16. ** The most liquid 3-year Korean treasury bond yield rose by 2.3 basis points to 1.521%, while the benchmark 10-year yield rose by 2.0 basis points to 2.020%.
