Insurance scam? Industrial accident? Political machinations? After August excursions to lands of clean air and English-language media, the Sinica team is back this week with a show covering the astonishing explosions that gutted the Binhai economic development zone in Tianjin last week. As the Chinese government struggles to deal with public pressures for greater transparency and conspiracy theories mount, we take a closer look at what we know and don't about the port explosion.Enjoy Sinica? Join Kaiser Kuo and David Moser this week as they talk with two journalists who covered the aftermath of the Tianjin explosions in person from the Chinese equivalent of ground zero: Julie Makinen who heads the China bureau for the LA Times and Fergus Ryan who covers China for The Guardian.
