Mother Teresa of Calcutta has been beatified that's why we now call her Blessed, but has not been canonized as a saint yet. Many consider her as a saint, even when she was still alive!
The evangelization of non-Christians should be the top priority of the Orthodox Churches and not center their efforts on us, Catholics of the East and of the West. We are, equally, apostolic Christians and we are on your side!

If ever, train your sights on the Protestants who are now more numerous than Orthodoxy combined. Probably, there are more Protestants in Russia and in her former vassal States than Catholics these days!
Protestantism is still a force to reckon with in the U.S. Are you doing something about it? What has the membership of certain Orthodox jurisdictions in the WCC and NCC done for Orthodoxy?
How about Muslims, Hindus, and Buddhists? There are about 1.2 billion Muslims worldwide (and do you still remember that Islam has nearly wiped out the traditional Orthodox lands in the East?) and 800 million Hindus and 300 million Buddhists!
Orthodox evangelization of China. Did you know that the last surviving (Russian) Orthodox priest in China died about 2 years ago and no Orthodox Church (Russian or otherwise) is currently being used as such anywhere in mainland China? The old priest's funeral was held in a Catholic Church presided over by a Catholic priest, although of the CPA kind. Yes, there is a dozen or so native Chinese in seminary training in Russia and, if ordained, will go back to China to minister to about 3,000 remnants of the Chinese Orthodox Church. The Russian Orthodox Church is building a Church inside the Russian Embassy compound (clearly to minister to Russians) but that's it for now.
Ditto for Orthodox missions to other parts of Asia and to Africa. Too little too late, if I may say so. How could you then be successful in converting Roman Catholics when you have seemingly abandoned the injunction of Our Lord to bring the Gospel to all peoples and nations? Roman Catholics are all over the world, of different peoples, of at least 176 countries, of differing cultures, of so many languages!
Asia is home to 2/3 of all humanity, or over 4 billion souls! Where are the Orthodox missionaries in these lands? Catholics now number about 120 million in Asia.
Africa is now home to about 150 million Catholics and rapidly growing. Are the Orthodox experiencing the evangelization spirit there? How do you like trying to convert animists and Muslims in the hinterlands of Africa or often warring tribes?
Much of the world is free to convert. And that's including us, Catholics!
But, please, do try to convert you backyard first!
