China always help the overseas Chinese who help themselves. China helped Chin Peng/MPLA, Chinese Vietnamese refugees, Chinese Indonesian refugees (the ones who accepted the evacuation offers anyhow), Kokang and Chinese in Yemen and Libya.You owe us blood debt and you must pay back ingrate! Those Chinese in Congo are Chinese citizen if you bother to care Yes we have overseas chinese representative in national congress , We also have overseas Chinese directorate with ministerial level So it is recognition that overseas Chinese is part of Chinese nation period! You fool!
What they had in common was that they were all unapologetically Chinese and were willing to be helped. Overseas Chinese have to be willing to accept help to get help. Not everyone is OK with accepting help. Those who refused to be helped... There's nothing to be done.
