A little better border + transit rights on Amur are important in securing Baikal region + future settlement of Okhotsk.
In OTL Golovin was intimidated by skillful military display of Chinese, believing their forces being twice as big as they actually were. With different commander (I used Sheremetev Senior who actually commanded the Tobolsk squan OTL for A&D TL) things may change for a little better border.
Well, I'd say that Okhotsk would be on a bottom of the list of the arguments.
To start with, in OTL Okhotsk was already on the map (founded in 1647) and "lost its importance after the
Amur Acquisition in 1860" so you are arguing for its earlier demise. Then, even if it had an usable harbor, it was just a coastal settlement, not a port (settlers did not have seagoing skills) and initial access to Kamchatka was by land until 1715 when the 1st ship had been built there (in 1736 location of the settlement had been moved couple miles downstream). In practical terms, its importance was questionable. Even if it was formally a base of the
Siberian Military Flotilla since 1731, by 1742 settlement had less than 100 buildings and 8 ships in a harbor (it took Bering something like 2 years to build 2 small ships for his expedition: every nail had to be carried across Siberia). Its importance grew only after the Bering's expeditions found sea otters east of Kamchatka: fur hunters began island-hopping along the
Aleutian Islands. Furs were brought back to Okhotsk and carried inland, mostly to be sold to the Chinese at
Kyakhta. Surely, Golovin & Co could not foresee this discovery. Besides, the site was poorly chosen: the harbor was bad and there was too little of a plowland so that most of the food had to be imported. The big ships could get in and out of the harbor only with the an incoming or outgoing high tide and proper wind direction, etc.
So the better (much better) deal would mean an earlier version of Amur Acquisition would allow to establish the better communications with the Pacific Coast. However, until Bering's expeditions value of the Pacific coast was too close to zero to fight for it seriously. OTOH, even before 1860 situation started changing noticeably. In 1850 - 53 Nevelskoy founded
Nikolayevsk-on-Amur and other forts on the Chinese territory, in 1851 the host of
Transbaikalian Cossacks 20,000 strong had been created and Manchu governor could do nothing to prevent
Nikolay Muravyov from sailing down the Amur with a convoy of 1,000 people. In 1855 Muravyov sent a 3,000 man force down the Amur, including settlers. The Chinese declared this to be illegal, but did nothing and he kept sending more settlers every year until ij 1858 the local governor had been forced to sign Treaty of Aigun. But, I repeat, all this became possible and practical with the conditions being substantially different from those of the late XVII.
Then, look at the situation from the ROI perspective: costs vs. profits. A protracted military conflict with China would mean interruption of the trade and loss of the revenues (and valuable imports) plus it would mean a permanent significant military presence far away from the places where the troops were really needed: southern and western borders. Neither would regional demographic situation allow to maintain any significant military presence based on the local resources. Treaty of Nerchinsk established a regular trade, which was the main Russian goal. "Golovin accepted the loss of the Amur in exchange for possession of Trans-Baikalia and access to Chinese markets for Russian traders." This is why the whole thing was considered as a success by Sophia's government (and by pretty much everybody else at that time).
To say frankly, I don't believe that overpromoting in-laws will stop overnight with the abolishment of mestnichestvo/place priority, and they will still have high positions in government.
They may or may not. Actually, when Peter finally started ruling the Naryshkins did not get high in his government (
Kirill Alexeyevich Naryshkin was governor of Moscow 1716-1719) and the 1st (and perhaps the only) really significant statesman in the family was Prince
Alexander Lvovich Naryshkin (1760–1826). Peter's uncle, Lev Naryshkin, was for a while a head of the Posolsky Prikaz (to be replaced by Golovin in 1699). Lopukhins never made it into power. Saltykov family was reasonably prominent оn their own but did not became power behind the throne even during the reign of Anne. There were 2 fieldmarshals in the family but the 1st of them got his rank during the reign of Elizabeth after his victories in the 7YW. Members of Apraxin family was linked to Fedor III but made their careers under Peter, etc.
OTOH, Ilya Miloslavski, while got some high positions at the court of his son-in-law, Tsar Alexey, never was respected by the Tsar who quite often was dressing him down in public. Ivan Miloslavsky made a great career but he was seemingly a capable person (who got a bad PR by the reasons obvious
).
It's just that OTL Saltykovs are not the best variant, nor is the exclusive relying on Sophia's friends. Golitsin is good, but not be all end all good.
Well, if he would seriously try to implement all reforms attributed to him, he would most probably end approximately as he did in OTL: abolishing serfdom was a high risk proposal. But if he is in power for quite a while he can establish a good framework for the future developments which would not be associated with a maximum pain level.[/QUOTE]
