It's not for certain Nigeria is going to be an enemy. China is still working diplomacy on them. With countries like that, it's possible to flip them rather fast just by finding the right opportunity.
In fact they're opposing some Russian acts in Niger, but that doesn't necessarily mean they are completely controlled by the west. China could use the situation to draw both Nigeria and Niger towards itself.
Things are not black and white, the ways China can act through Russia isn't just in mindlessly making Russia bigger. They can also use Russia as a boogeyman to drive countries like Nigeria into making the correct decisions.
What China is doing across the board is moving random "global south" countries to do decisions that make America lose face. They know face is one of America's biggest weaknesses and that US will waste time/effort/money on overreacting when that happens.
