In the affairs of the world, many different paths lead to the same destination.
Sergei and Gao Guang are doing almost the same thing, except Sergei is exchanging nuclear bombs for money, and then using the money to gather a group of people onto his ship to help him climb to a higher position.
Gao Guang is exchanging money for nuclear bombs, and then he plans to use the nuclear bombs to tie a group of people to his chariot, not pursuing money, but a crownless king's status.
So it's not that Gao Guang saw through Sergei's conspiracy, nor that Sergei discerned Gao Guang's plan; they simply have similar insights and happened to act at the same time.
Gao Guang does not know what position Sergei is seeking, but judging from Sergei's attempts to find a promotion path while ensuring a fallback for his family, it must be at least two levels higher than his current position, likely a position like the Minister of Internal Security, but at least a department head.
