Acting President and Prime Minister Hwang Kyo-ahn on Wednesday pledged to ensure "sufficient communication" with parliament, in an apparent move to placate opposition parties wary of his growing assertiveness.

"(I) will solemnly uphold the will of citizens and reflect it well in the entirety of state affairs," he said during a meeting with National Assembly Speaker Chung Sye-kyun. "In the process, I will ensure sufficient communication with lawmakers led by the Assembly speaker."

It marked Hwang's first visit to the legislature since he took over as acting president last Friday following the impeachment of President Park Geun-hye over a corruption scandal involving her and her longtime confidante.

The meeting came as opposition parties are moving to tame the interim leader who has actively engaged in the running of the country contrary to the earlier expectations that he would remain low-key.

Three opposition parties, led by the main opposition Democratic Party, have called for a meeting with Hwang to discuss the scope of his engagement in state affairs. But his office has shown reluctance to engage in the opposition-dominated gathering. (Yonhap)
