My speculation and this is the best case scenario: one year after buying into CCME, Starr found it is not the innocent boy that was presented to them during the fact-finding phase. West-east cultures clash: money is not controlled the way Starr wanted, Foreign Business Conduct Act is not been upheld, etc. It gets hot in the board room sometimes.
DTT was hired at Starr's request back in 2009, when the party are at good terms. DTT did its standard audit and signed off the 10-K.
In 2011, differences between Starr and CCME became serious and Starr was trying to leverage DTT to bring CCME into compliance. Yet, Mr. Cheng and his local management team (Jacky is from HK and not part of the inner circle) continues to be defiant.
DTT is under pressure to cover its own behind, especially with all the short seller attacks and anonymous emails. Also, Starr wants DTT to produce the talk points so it can tame the local management.
Mr. Cheng is not going to change. So the resigns.
