Of course. The deal is, then, that you gain rights to the area given to you in the Urals as well as trade and benefits as to the favoured trading system of purchasing rare minerals and metals in exchange for us supplying you with whatever goods you may require in trade and you helping us with the construction of a Mag-Lev network between our cities of Moscow, St. Petersburg, Vladivostok, Rostov and Stavropol.

As for your sovereignty, we would suggest taking it to the EU, as the nation with the most authority in international matters. To be formally recognized as a country you will need to have undisputed claims to sovereign territory, which in today's world might be difficult; unless you're based on Antarctica there's no place on Earth not claimed by someone. Or in space, apparently, looking at the NWF. We're willing to offer you diplomatic sovereignty on the Ural Arcology, akin to what embassies of foreign nations get, once you gain official recognition for the status. Before that, our legal system will treat you as a foreign corporation with extraterritoriality on your land.
