President Lee Jae Myung appears to be trying to restore political momentum after returning from a 10-day diplomatic tour of Europe, Thursday, amid declining approval ratings and tensions within the ruling Democratic Party of Korea (DPK).

On Friday, the president convened a press briefing on the outcome of diplomatic trip, which concluded Thursday, and also a meeting with senior presidential secretaries.

The briefing was held amid speculation that the president believed the achievements of his trip had been overshadowed by domestic political issues, leading him to personally present the results instead of delegating the task to aides, as is customary.

Meanwhile, Friday's meeting with senior presidential secretaries followed a previous gathering with corresponding aides in Seoul, Sunday, while Lee was in Italy for a state visit.
