Masila,
ClinicalTrials.gov listing for BETonMACE hasn't been updated since October 27, 2015. Those same 11 countries have been there all along. Nothing has changed recently on ClinicalTrials.gov.
I've been tracking the changes on ClinicalTrials.gov and EU Clincal Trials Register regularly. Here is my most recent observation. The only thing that has changed is the occasional listing of one of the 12 countries on EU Clinical Trials Register.
As for who the 12th country is, take notice that EU Clinical Trials Register lists Austrailia but ClinicalTrials.gov does not. If China is involved, that would be the collective 13th country. I'm not sure why Austrailia is listed on one site but not the other and not sure what the deal is with China.
