Jeong Jae-heon, chief executive of SK Telecom, departed on April 22 to join President Lee Jae-myung’s economic delegation on a trip to Vietnam. Jeong attended the opening event of the World IT Show in Seoul earlier in the day and visited SKT’s booth ahead of the opening to check preparations. Leaders of South Korea’s four major conglomerates are also expected to join the delegation.

LG Uplus said on Wednesday it signed an agreement with LG Electronics to jointly pursue early research and development of AI-based communications technologies for the 6G era and to cooperate on international standardisation. The companies plan to strengthen cooperation in key next-generation areas including semantic communications and post-quantum cryptography. They will review network applicability, security requirements and standardisation issues, and hold an annual technology exchange meeting to further shape cooperation.
