Isa, I had a very poor choice of words when I said that the Chinese Orthodox Church no longer exists. What I should have said is that its organizational structure had basically been decimated. If I am wrong on that, feel free to correct me.
Decimated, that's true enough. But not abandoned. There has been a lot of low key activity between Russia and China which, as always, has always been tense over the Church.
As to the EP's claims on America, I don't think it had any more of a right to claim jurisdiction over the country. It was also a great misfortune that the Patriarchate established a cathedral in San Francisco, it should have only set up bishops in areas without them (preferably regions of the countries, or at least States, without them). As to your claim about the Alaskan cessation treaty, could you point me to the passage because I've never heard that before (I believe you, I just haven't heard that)?
The bare clause is this:
In the cession of territory and dominion made by the preceding article, are included the right of property in all public lots and squares, vacant lands, and all public buildings, fortifications, barracks, and other edifies which are not private individual property. It is, however, understood and agreed, that the churches which have been built in the ceded territory by the Russian Government, shall remain the property of such members of the Greek Oriental Church resident in the territory as may choose to worship therein. Any Government archives, papers, and documents relative to the territory and dominion aforesaid, which may now be existing there, will be left in the possession of the agent of the United States; but an authenticated copy of such of them as may be required, will be, at all times, given by the United States to the Russian Government, or to such Russian officers or subjects as they may apply for.
The inhabitants of the ceded territory, according to their choice, reserving their natural allegiance, may return to Russia within three years; but if they should prefer to remain in the ceded territory, they, with the exception of uncivilized native tribes, shall be admitted to the enjoyment of all the rights, advantages, and immunities of citizens of the United States, and shall be maintained and protected in the free enjoyment of their liberty, property, and religion. The uncivilized tribes will be subject to such laws and regulations as the United States may from time to time adopt in regard to aboriginal tribes of that country.
That doesn't say much on the surface, but you put in the context of American law, and its a big deal. I don't have the time right now to cite the common law on this, the case law, newspaper articles, etc. as I've done here and at http://orthodoxhistory.org/
, but for an overview: as a treaty, according to the supremacy clause, it is supreme law of the land, so although, for instance, the First Amendment does not allow establishment of religion, the citizenship of the natives was determined in part by whether they were Orthodox or not. Not only the Orthodox Churches, but the Lutheran ones (because of the status the Czar and St. Innocent gave them), were taken as automatically incorporated, amongst other oddities, because according to US law the prior law of a territory annexed by the US is treated as American, not foreign, law. The status of the Orthodox diocese of Alaska was like the status of Guantanomo Bay, where the US has the port, but Cuba has sovereignty. The Czar ceded sovereignty to the US government, but the Church maintained its status, but now as an American institution, due to recognition in all the states due to full faith and credit.
