Africa's biggest oil producer, Nigeria and Angola, were among several countries given lower output targets for 2024 after years of failing to meet the previous ones.
Angola said on Thursday OPEC no longer served the country's interests.
But Nigeria's minister of state for petroleum Heineken Lokpobiri said in a statement that the country's commitment to OPEC remained unwavering.
"Our collaboration within the organization remains pivotal in fostering stability and sustainability in the oil market," Lokpobiri said in a statement.
"We are resolute in our dedication to OPEC's objectives while actively engaging with the organization to address concerns that resonate not only within our nation's borders but across the entire continent."
Nigeria was given a 2024 target of 1.5 million barrels per day (bpd) but says it plans to produce at least 1.8 million bpd.
