If you have the necessary experts in country. Russia of the 1920s suffered from serious brain drain besides capital flight. Does TTL USSR still cut a deal with Germany in the 1920s? Do they hire foreign experts from abroad like Fred Koch?
They did not have too many options and part of the NEP involved invitation of a foreign capital (or course, there was elaborate schema of how to cheat these companies later but this is a different issue). Buying equipment and attracting specialists also was going on, hence the massive sale of the confiscated jewels and works of art.
