Mr Mwamba said Zambia and Malawi should strive to ensure that Southern African countries remained a haven of peace through such fora as the JPC.
He said the session was another milestone of cooperation in peace and stability to which the two countries had committed themselves.
The minister said President Michael Sata and his Malawian counterpart Joyce Banda had shown commitment to ensuring that issues affecting the two countries were addressed amicably through the JPC.
He reaffirmed Zambia’s commitment to fighting border crime, smuggling, human trafficking, and other vices that may affect the economic development of the two countries.
Earlier, Malawian Defence minister Kenny Kandodo said the JPC was an important instrument in bringing close cooperation, peace and security between the two countries.
Mr Kandodo said improved peace and security along the border had promoted socio-economic development and should be embraced at all times.
He paid tribute to the leadership of the two countries for their support towards the ideals of the JPC that had led to greater cooperation in the promotion of peace and security between Malawi and Zambia.
He said the just-ended meeting provided an opportunity for the two countries to review what had been achieved and what was not yet achieved.
The Zambia/Malawi JPC opened on Monday in the tourist resort town of Mangochi to discuss cross-border crime, smuggling and human trafficking, among other issues.
