In 1993 CORD (Christian Outreach Relief and Development) started its operation in Prey Veng province which is located in the south-eastern part of Cambodia. The aim of the operation was to provide support and assistance to poor people in Prey Veng province. CORD launched two projects — one was called ― ABCD (Agriculture Business and Community Development). Another was called ― EFGH‖ (Education For Good Health). In1998, based on strategic planning in order to promote sustainable local development, a local non-governmental organization Ponleu Ney KdeySangkhum (PNKS), means Light of Hope, was localized from CORD to handle the ABCD project. PNKS, a Christian non-governmental organization, was officially registered with the Ministry of Interior in January 2001.

In 2001, CORD took over an integrated rural development project, Community Development Assistance Project (CDAP) in Kampong Speu Province, started by ZOA in 1998. Over a period of six years CORD reduced its role while initiating a range of capacity development strategies within PNKS. Finally in 2004, EFGH (Education For Good Health) and CDAP, then it was called Somleng Kampong Speu project, meaning voice of Kampong Speu were handed over to PNKS. CORD has continued to support PNKS.

At the beginning of 2006, the ABCD project was integrated together with the EFGH project, the combination of these two projects comprises a program called "A2H "program. The year 2006 marked the transition year for the merging of the two projects. The plan to merge the ABCD and EFGH into one program was aimed to better serve the target group of each project by integrating planning, management and monitoring of the projects. The project was then called "Somleng Prey Veng project", means Voice of Prey Veng, being consistent with another project in Kampong Speu which is called "Somleng Kampong Speu project.

PNKS Somleng Program currently has two projects — Somleng Prey Veng project (S-PV) based in Prey Veng province and Somleng Kampong Speu project (S-KS) based in Kampong Speu and Kampot. The Somleng program will focus on improving community health, income generation and community empowerment focusing on human rights, advocacy and social accountability.
The Somleng program will continue support to already existing partners and target areas, 58 villages, where majority PNKS entered in 2011, some in 2012 and some in 2013. 11 villages in Prey Vengis only focusing health.
