SEOUL, March 24 (Reuters) - Round-up of South Korean financial markets:

** South Korean shares ended lower on Thursday, slipping from a three-week high hit in the previous session, as higher oil prices fuelled inflation worries, while the Russia-Ukraine conflict sapped risk appetite. The Korean won weakened, while the benchmark bond yield rose.

** The benchmark KOSPI closed down 5.39 points, or 0.20%, at 2,729.66.

** Chipmakers Samsung Electronics and SK Hynix fell 0.99% and 2.43%, respectively, leading the declines in the index, while battery maker LG Energy Solution rose 0.25%.

** The stocks tracked an overnight selloff on Wall Street as oil prices jumped, while Western leaders began gathering in Brussels to plan more measures to pressure Russia to halt its conflict.

** Russian President Vladimir Putin said Moscow will seek payment in roubles for natural gas sales from "unfriendly" countries, while its forces bombed areas of the Ukrainian capital Kyiv a month into their assault.

** At home, South Korea's nominee for its new central bank chief said on Thursday worries about inflationary and economic risks are mounting and that he would thoroughly review how to manage growth, price pressures and financial imbalances.

** Meanwhile, some $1.1 billion worth Samsung Electronics shares were sold in a block deal by Kookmin Bank on Thursday, according to a term sheet seen by Reuters.

** Foreigners were net sellers of 473.5 billion won ($388.52 million) worth of shares on the main board.
