With all due respect, so many times people (domestic and aboard) considering China's voice, especially regarding utilizing military forcese, are more theoretical than practical, if not lip services - how could everyone so firmly sure this time, is the real one?
Gen Chen's opinion can be well consider as trying to persuade THE OTHER powerhousese to take more initiative on strike the piracy at the root, than actually sugguesting putting PLA boots on Somalian soil. PLA personnel never been good at make a diplomatic statement, but they never step out the policy made by the centre government (in this case, Politburo), which in no other occasion China has expressed such intention (oversea deployment). Not to mention the diplomat.com twists points around for their own reasons, as we well aware.
Besides, 2012 is a massive political shifting year which all over the world having all kinds of administration shifting / election. I would watch and listen more seriously, after the CCP's 18th grand congress session, (and USA's GOP), than of now. To me, diplomat.com is doing more lip service than Gen Chen this time.
