It won’t be for long... Sanya (the island next door) is already expanding there ports as per government planning quietly. They publicized it to be the next Shenzhen, but in reality there using the docks to replace the import/export of Hong Kong. The step next year will be to reduce the import/export taxes lower than HK so that businesses will go over to use them. It’s all part of the government planning in PEK, just wait for reality next year...
