I don't believe so. ODESSA in this context is the name given to both an alliance of nations and factions; and to the protocols they have agreed to adhere to. The Bezerk thread understanding is that ODESSA deals specifically with the organism problem, and was most likely initiated by the Russians - who clearly seem to have some 'history' with the organism (from the Antarctic I suspect). ODESSA includes Russia, Germany and France, plus the US Navy was aboard last time I heard. ODESSA seemed to have some type of weapon or radical plan, which was referred to as OMEGA.

China was obviously invited aboard ODESSA, but never seemed to accept. It would now seem that they had their own information about the situation that they did not see fit to share at the time. That is my impression from reading all the relevant posts at the Bezerk thread.
