The PLA has also been shaken by a separate corruption scandal in the run-up to the party leadership change, said Chen Ziming, an independent scholar of politics in Beijing."I think both incidents generated tensions and uncertainty, and in the military the case of Gu Junshan is a source of tensions," said Chen, referring to PLA Lieutenant General Gu, whose downfall for apparent corruption emerged this year."Before previous recent party congresses, the Internet was not such a factor, and structural factors, including the big turnover of leaders, are adding to uncertainty now," he said.
