Sheng Shiong - no ban on sharks fin?

So, after NTUC Fairprice decided to stop selling sharks fin, most of us were wondering whether the other supermarket players would join in too.  Cold Storage was the first to implement a "no sharks fin" policy (well, it was in Oct 2011) but Giant and Shop N Save, which are under the same parent company still sell sharks fin products.

This was what was on Sheng Shiong's Facebook page:

"Hi All,

Thanks for your patience with regards to the sales of shark's fin at Sheng Siong.

We've reviewed the matter extensively and decided that there is no plans currently to stop selling shark's fin. 

However Sheng Siong will scrutinize its future supplies of shark's fin products to ensure that the sources are not from inappropriate shark finning. 

With regards to some concerns about the sales of mola mola meat, Sheng Siong is currently not selling this item and do not plan to do so in future. 

We appreciate all the feedback that has been given."

I honestly don't understand what "ensure that the sources are not from in appropriate shark finning" is? Do you?
