Answer:
This is a violation of the Foreign Corrupt Practices Act (FCPA)
Step-by-step explanation:
The Foreign Corrupt Practices Act (FCPA) is a United States government law enacted in 1977. It prohibits practice of bribe payments to foreign officials with the aim of retaining business or gaining contracts.
This law covers those with ties to the United States and those that violate the law within the United States.
So nationals of the US must obey FCPA regulations even when they are outside the country.
In this scenario the action of Oswaldo officials who paid the bribes and were awarded the contracts, considering this as a necessary cost of doing business is a clear violation of FCPA regulations
