Clarification, rank and file enlisted/officers are professional. The general ranks are half and half. You don’t hear too much of any new PLA scandals because the Communist Party has reined in the generals from making PLA into a private enterprise. This came about because many of the PLA arms sales were private actions and not necessarily coordinated with the PRC foreign policy objectives. A number of times PLA arms were sold to insurgents while the PRC was trying to establish more favorable relations with the existing government. Remember the PLA donations to Clintons campaign? The PLA general responsible for the project was sacked because the PRC was trying to negotiate some trade issues with the US that needed Congressional approval. The general did not inform the CCP when he initiated the money laundering until the operation was well underway. The scandal played a role in electing GWB over Gore.
thanks for your comments, you are better informed on this than I am.
