North Korea viewed the NNSC as existing in name only after the inspection teams were withdrawn.
A 1970 report on the NNSC by the U.S. Arms Control and Disarmament Agency concluded "Since the NNSC was established only to observe the enforcement of 13(c) and 13(d), it ceased, therefore, to have any function."

The Historian of the NNSC described this situation as:
The Americans and South Koreans, no longer hampered by the presence of the Czechoslovacs and Poles and free to accelerate the modernization of their armament, now showed less haste to do away with a body which had ceased to inconvenience them and might even serve to restrain the propaganda against them by the North Koreans and Chinese.
The Neutral Nations Supervisory Commission thus remains a facade, maintained only because of apprehension about the void which would occur if it were abolished.

From June 1956 to 1993, the NNSC ceased their controls but solely forwarded the war parties' reports on entering and leaving military persons to the UNCMAC.
The strengths of the delegations from Poland, Czechoslovakia, Sweden and Switzerland were reduced gradually: On 9 June 1956 to 14 members each, in 1960 to nine members each, and in 1978 to six members each.
Residing inside the Joint Security Area (JSA) are the offices and conference room for the NNSC.

Camps for the Swedish and Swiss members and their staffs are located in the southern half of the Korean Demilitarized Zone (DMZ) adjacent to the JSA.
The former Polish and Czech camps which were located nearby on the north Korean side of the Military Demarcation Line, have been taken over by the KPA and are now used for other purposes.

Following the collapse of communism leading to Czechoslovakia and Poland joining NATO, and the dissolution of Czechoslovakia into the Czech Republic and Slovakia in 1993, North Korea believed the NNSC had lost its neutrality, and took the view that the NNSC had collapsed.
North Korea expelled the Czech component in 1993 and the Polish component in 1995.

Since 1995 North Korea has not recognized the existence of the NNSC.
The Swedish and Swiss delegations continue to submit reports on South Korean troop movements to North Korea, which are ignored.
Poland continues to attend NNSC meetings, although it is no longer able to observe troop movements in North Korea.
