SEOUL, July 23 (Reuters) - Samsung Electronics ( SSNLF )

and representatives of its biggest workers' union in

South Korea, which has been on a strike, met on Tuesday but the

talks ended without results, the union said.

Since earlier this month, the union has been on an

indefinite strike over pay and benefits.

The gap between the two sides is too wide to reach any

agreement, Lee Hyun-kuk, vice president of the National Samsung

Electronics Union whose roughly 30,000 members make up almost a

quarter of the company's South Korean workforce, said on a

YouTube live broadcast.

Union officials called on the company to bring a fresh offer

to the negotiating table by July 29 and plan to hold ultimate

talks with the company through July 31, they said.

Analysts have said a drawn-out strike by key personnel will

add to challenges for Samsung, the world's biggest memory

chipmaker, which is struggling to navigate competition in

semiconductors used for artificial intelligence.

Samsung has said the strike has caused no disruption to chip

production.
