Zeliang was responding to a question on summoning of three CMO officials by the National Investigation Agency (NIA) for interrogation.
"They (CMO officials) will be going and explaining their position," he said.
The NIA has jurisdiction to investigate if payment is being made to terrorist groups, he said.
"Like in Nagaland the NSCN(K) has been declared a banned organisation. If anybody is paying them it becomes illegal but, the CMO has nothing to do with NSCN(K) or any other organisation," he said.
Zeliang said on November 21 last year state government officials had submitted a memorandum demanding the recall of the NIA from Nagaland, alleging that they were being harassed.
The NIA had yesterday issued summonses to three CMO officials to its branch office in Guwahati for interrogation tomorrow.
The NIA was investigating the extortion cases in Nagaland since August 2016, sources said while also alleging that incriminating documents were seized where the involvement of three CMO officials was detected.
