The air is getting thinner and thinner for China’s ousted Minister of Agriculture and Party Secretary Tang Renjian. Following his dismissal from office in May and his expulsion from the Communist Party in November, he has now been officially arrested. The highest public prosecutor’s office accuses Tang of taking bribes in the performance of his duties. His conviction is considered very likely. No high-ranking party cadre has ever been cleared of the charges in a comparable case in President Xi Jinping’s anti-corruption campaign.
