China and Russia enemies
At the beginning of this film it was mentioned that the Soviets were going to sell one of their old subs to the Chinese along with some other outdated military hardware.
However by 1968 when this story takes place China and Russia are no longer on friendly terms.
Due to political differences the 2 communist nations were no longer cooperating on anything.
And the Soviets were certainly not supporting them militarily either by this time.
So why would they be giving them any military hardware? Even if it was old obsolete stuff
they no longer needed.
This doesn't quite sound right to me.
It is difficult to free fools from the chains they revere.
