Conservative leader Martin Dowey has vowed to 'unfriend' the Chinese city of Liaocheng on "day one" if his party are elected in May.
However, Deputy Council Leader Brian McGinley said those opposed to South Ayrshire Council's friendship agreement lacked "vision, ability and commitment" to build bridges with China.
Last week it was revealed that MI5 had warned of an alleged Chinese agent they said had "infiltrated" Parliament in a bid to interfere in UK politics.
