中国地方政府要求恒大汽车退还19亿元补贴

5月22日晚间，恒大汽车在港交所公告，附属公司恒大新能源汽车于近日收到相关地方行政部门下发的函件。要求退回已发放的各项奖励及补贴合计约人民币19亿元，相关附属公司并需互负连带责任。相关附属公司自2019年4月29日起与相关地方行政部门签订一系列的投资合作协议。因本公司未按相关协议的相关条款约定履行合同义务，拟要求相关附属公司解除相关协议。恒大汽车承认，上述函件要求如最终执行，会对公司或各相关附属公司的财务状况和经营产生重大不良影响。

看到这个消息就查了下，当时投资恒大汽车的地方政府有广州、天津、南京、上海、南宁、沈阳，这难道不算国家行为吗？咋就地方政府了？

政府总想和恒大做切割，殊不知在国内搞房地产，开发商就是政府的手套。

台湾曾经是战争和流离的产物。曾做过副总统的吕秀莲形象地说，台湾就像件战利品，日本打赢了，就送给日本，日本战败了，又送回中国，成了中华民国的幸存和偏安之地。独特的历史造就了台湾独特的现实：几分中国、几分日本、几分欧美，几层东洋、几层西洋、几层传统、几层现代，层层叠叠，让人处处感受到不易辨识和言传的离散与融合。作为离散的中国人，徜徉其中，总能感受到几分亲情，几分敬意，也不免有几分失落和遗憾。
