I've heard that this plan included "Clearing Great Fire Wall" to provide free internet service.
But, when we consider that Beijingsensorship strictly strengthens its censorship against anti-government movement and tries to install Great Fire Wall system, it would be impossible to remove Great Fire Wall in Hainan. Amid rising conflicts between US and China about trade, free port plan itself must be stumbling. In this situation, we cannot expect any advancement about this measure.
