Kausikan’s megaphone diplomacy? Or is it Singapore’s megaphone diplomacy?

The last article by Bilahari Kausikan attacking China’s covert and overt diplomacy has stirred the hornet’s nest among Singaporeans doing business in China. Many were irked by his unnecessary hostile remarks against China in a forum of American and western audience, in his words, exposing China for influencing and manipulating the policies of govts to favour China. No matter how he slithered to claim that he was not attacking China in particular, no one is going to believe him as the intent of this article was as clear as a bright Sunday morning.
 
Many people have written to the forum pages of the ST to show their displeasure of his hostility towards China. In the ST forum page of 9 Jul, a Lim Ang Yong was equally incensed to question his intent and even suggested that it was Singapore’s megaphone diplomacy that was not good for Singapore China relations.
 
Let me quote Lim Ang Yong, “It seems unwise to shame China in a forum co hosted by American based organizations in front of an international audience. It is also true that we should educate Singaporeans, but that was not the goal of that forum, neither is it the role of a private individual. I am sure it is not the Govt’s intention to let former ambassadors be its proxy voice or lead its thinking and decision making on managing its China relations….”
 
Lim also noted that Kausikan was a former perm sec and diplomat and his knowledge of China interfering with Singapore’s policies were classified and sensitive information obtained while in office. These were privileged information protected under the Official Secrets Act that no ordinary peasant would be accessible to. All civil servants privy to official classified information are under oath to protect such information while in service or out of service and disclosing such information is an offence under the OSA. In his over zealous attempt to discredit China, has he crossed the line and divulged classified information protected under the OSA?
 
Has Kausikan’s disclosure and exposure of China’s behavior violated the Official Secrets Act as what he knew and said about China were privileged information available to him while in office?
What do you think?
 
PS. Lim Ang Yong also asked this question. “Did he get approval to speak as if he were an authority on the issue for the Singapore Govt?”
