It certainly seems from the statement that they're against the holding of any orcas there. It makes me think they may not go and acquire any more from China and either let Naja remain there in solitude, or send her elsewhere.They've always claimed in their promotional material (and I am guessing displays to visitors) that these three were rescued from poachers. Could be financial issues behind the scenes caused by current world events, I am unsure who the people are behind these companies so that could be a problem?
It's very possible that the change on the stance of cetacean capture in recent years over in Russia may be behind this change by the Moskavarium. That, or maybe even new management who are against captures.
