I doubt that since any declaration or statement citing repeatedly Ukraine's territorial integrity, international obligations, will of particular ethnic groups having direct interests or acting as proxies for foreign powers involved in religious supremacism worldwide voluntary ignoring in these declarations or questioning the legitimacy, up to the legality of  the former USSR decision to dispose of a Land and its People in this instance Crimea without a formal democratic consultation while failing to recognise that the legal status of Ukraine at the time of the decision and its relation with Russia within the USSR made the move for the Crimean Nation of much less significance that it would have been had Ukraine had the same status it has today. Therefore a statement or declaration aimed at appease ethnic tension and will, pursuing peace and respect for the core interests of the majority as well as minorities rights within Crimea suppose a true and sincere evaluation of what would have been the Crimean Nation will had its People been "given" to Ukraine under its news status modifying considerably the nature of its relations with Crimea and Russia and acknowledging that the change of loyalty it imposes on the Crimean majority cannot be ignored no more than can be ignored that it cannot be taken lightly or should require a sincere open consultation. Failing to do so disqualifies these statements or declarations to be pursuing appeasement and good will, they are rather pursuing special interests and a factor promoting lawlessness. The change of Ukraine's status and the change in nature of the relations with the Russian Federation are so substantial compare to when the decision was made then by the former USSR that the consequences it imposes on the Crimean People should lead to a thorough investigation of the legal rights of the Crimean People to exercise a recourse against the first decision made to dispose of their Land and their loyalty.
I'd stick to that for now.
