South Korea will step up its participation in global peace-keeping operations, the military official in charge of foreign troops dispatch said Friday, as the country marks the three-year anniversary of PKO deployment in the violence-hit South Sudan, Yonhap reported.

With the 5th rotation of forces of the 290-strong "Hanbit" unit arriving in the South Sudanese town of Bor this week, South Korea marks three years since the dispatch of the rebuilding forces.

The Hanbit unit was dispatched to the town, located some 170 kilometers north of the capital Juba, in July 2011 while the newly-independent South Sudan was reeling from decades of civil war.

Since the deployment, the South Korean unit has been tasked with a variety of rebuilding and peace-keeping missions under the wing of the United Nation Mission in South Sudan, including infrastructure building in the war-torn country as well as other humanitarian aid activities.

As the latest South Sudanese Civil War broke out in December 2013, "the Hanbit unit perfectly carried out its top priority UN mission of protecting civilians," Major General Oh Jeong-il said in an interview with a pool reporter, later released by the Defense Ministry.

"As our country owns the asset of being an economic success model, the role Hanbit could play in contributing to the development of South Sudan would be the transfer of development experiences," Oh noted.

As part of those efforts, the military will seek tighter collaboration with the Korea International Cooperation Agency, the official development assistance body, to better provide the services, he said.

As South Korea's other foreign-dispatched units, "Ahk" in the UAE and "Dongmyeong" in Lebanon, mark four and eight years of dispatch respectively, the country plans to reset strategies on its overseas troops deployment in a way it could maximize effectiveness, he said.
