The union said on Saturday that Samsung had replaced its lead negotiator ahead of renewed talks and that both sides would also hold a separate meeting later in the day. The company declined to comment on the discussions.

The announcement followed a public apology from Samsung Chairman Jay Y. Lee over the escalating labor dispute, marking his first direct remarks on the issue.“I sincerely apologise to customers around the world for causing anxiety and concern due to issues within our company,” Lee said in Seoul, adding that he also “deeply bows in apology to the public.

”Union leaders said Samsung’s newly appointed negotiator acknowledged a breakdown in trust and pledged to engage more sincerely in discussions aimed at resolving the dispute.

The South Korean government has stepped up pressure on both sides after mediated negotiations collapsed earlier this week, raising the prospect of a strike that officials warned could disrupt exports, financial markets and broader economic growth.

South Korea’s labor minister met Samsung management on Saturday and urged the company to take a more active role in resolving the standoff through dialogue.The union said on Friday it still intended to proceed with a planned strike next week despite Samsung’s proposal to restart negotiations without preconditions.

Concerns over potential industrial action have intensified because Samsung plays a central role in the global semiconductor supply chain. The company supplies chips to major technology firms including Nvidia, Advanced Micro Devices and Alphabet.

Government officials, including South Korea’s prime minister and finance minister, have warned that prolonged disruption at Samsung could have significant implications for the country’s export-driven economy.
