The GCC Secretary-General commended the UAE security agencies for their work in arresting an alleged cell of terrorists.
The group of Saudi and UAE citizens were accused of plotting attacks against the UAE and neighbouring countries.
Dr Abdullatif bin Rashid Al Zayani said their competence and alertness helped to thwart attempts to subvert the security and stability of countries in the region, according to Bahrain's state news agency, BNA.
The arrests, which were carried out on Wednesday, had been in co-ordination with security forces in Saudi Arabia.
Dr Al Zayani hailed the security cooperation between the GCC member states, stressing the importance of coordination to stave off any attempts to destabilise the region.
The Saudi Interior Ministry also praised the security achievement, according to Qatari newspaper, The Peninsula.
No further details of how or where the arrests took place, or how many were detained, have been released.
However, according to state news agency Wam, those arrested were members of an "organised cell from the deviant group that was planning to carry out actions against national security of both countries and some brotherly states".
Those arrested have been referred to the Federal State Security Prosecutor.
