* KOSPI rises, foreigners net sellers

* Korean won weakens against dollar

* South Korea benchmark bond yield falls

SEOUL, Jan 15 (Reuters) - Round-up of South Korean financial markets:

** South Korean shares rose on Monday as investors found comfort in China's decision to boost liquidity injections, while Taiwan's election results during the weekend also lifted sentiment. The won weakened and the benchmark bond yield fell.

** The benchmark KOSPI was up 5.33 points, or 0.21%, at 2,530.38, as of 0114 GMT.

** China's central bank boosted liquidity injections, but surprised markets by leaving the interest rate unchanged when rolling over maturing medium-term policy loans on Monday.

** Taiwanese voters swept the ruling Democratic Progressive Party's presidential candidate Lai Ching-te into power on Saturday, strongly rejecting Chinese pressure to spurn him, as China said it would not give up on achieving "reunification".

** Taiwan's election could allay global concerns about the island's relations with China, while prompting a light selloff domestically on Monday as investors worry the result could hinder economic policy.

** Among index heavyweights, South Korean chipmaker Samsung Electronics rose 0.82% and peer SK Hynix gained 0.45%, while battery maker LG Energy Solution slid 3.03%.

** Hyundai Motor added 1.02% and sister automaker Kia Corp gained 2.04%, while shares of search engine Naver were down 0.65% and instant messenger Kakao climbed 1.66%.

** Of the total 936 traded issues, 430 shares advanced, while 419 declined.

** Foreigners were net sellers of shares worth 91.1 billion won on the main board on Monday.

** The won was quoted at 1,316.9 per dollar on the onshore settlement platform, 0.26% lower than its previous close at 1,313.5.

** In offshore trading, the won was quoted at 1,318.7 per dollar, down 0.4% on the day, while in non-deliverable forward trading its one-month contract was quoted at 1,315.7.

** The won has lost 2.2% against the dollar so far this year.

** In money and debt markets, March futures on three-year treasury bonds rose 0.03 point to 105.19.
