The 53rd National Conference of the ANC, held in 2015, stated in its "Discussion Document" that "China economic development trajectory remains a leading example of the triumph of humanity over adversity. The exemplary role of the collective leadership of the Communist Party of China in this regard should be a guiding lodestar of our own struggle." It went on to state that "The collapse of the Berlin Wall and socialism in the Soviet Union and Eastern European States influenced our transition towards the negotiated political settlement in our country. The cause of events in the world changed tremendously in favour of the US led imperialism."
