That was Samir Amin's position, 'decoupling' he called it. But it was not Lenin's. He thought that the USSR ought to seek to continue to be a part of the international division of labour, exchanging goods for western technology, but should at the same time resist a free market. That would establish a direct relationship between Russian farmers and western purchasers, bypassing 'socialist industry' in the cities, and reducing Russia to a breadbasket. Lenin's mechanism was the state monopoly on international trade.
