"(Hungarian authorities) are investigating the case, and (we believe), based on the results of the probe, emphasis should be put on the thorough identification of those responsible (for the sinking)," Kang told reporters at Incheon International Airport.

Kang departed for Slovakia to attend multinational talks with the Visegrad Group of four central European states -- the Czech Republic, Hungary, Poland and Slovakia -- on Friday.

On the sidelines of the talks, Kang plans to meet Hungarian Foreign Minister Peter Szijjarto to discuss continued cooperation in handling the deadly sinking.

"I expect that (I and Szijjarto) will have in-depth discussions over the follow-up situations and what we will have to do down the road," Kang said.

After her visit to Slovakia, Kang will travel to Serbia on Friday to meet with top officials there, including Prime Minister Ana Brnabic, Foreign Minister Ivica Dacic and Interior Minister Nebojsa Stefanovic.

During the meetings, Kang plans to extend Seoul's appreciation for Serbia's support for search operations and call on it to further strengthen its operations along the border with Hungary.

Earlier in the day, Kang presided over a government disaster management session to discuss search and other operations at the scene, support for the victims' families, funeral procedures and investigations into the sinking.

At the session, participants also discussed whether there is a need to send more equipment and personnel to support search operations and ways to prevent the loss of any bodies and their belongings in the process of salvaging the ship from the riverbed. 

The Hungarian authorities have mobilized a large floating crane, named Clark Adam, for the work to lift the ship. But the crane is currently docked about 5.5 kilometers away from the scene of the accident, as it could not pass through the Margaret Bridge due to high waters.

Hungary has sought to finish the work to lift the ship by Sunday, but the process could be delayed due to high waters. (Yonhap)
