Answer:
Culture Training
If a company has to do business with people from another part of the world, the company should endeavor to train its staff in the etiquette required of them by the people of that country so as to avoid any unfortunate incidents.
They could hire a culture expert who would come around and give classes to the employees to get them ready for interaction with the other people.
Hiring a Culture expert
In addition to culture training, the company could hire an onsite culture expert who can advise the company on such matters. Such an expert would be able to offer expedient advice to the company as employees can simply go to them and ask for advice rather than going through a long class.
Such an expert could also vet the gifts that are to be exchanged with people of other cultures for appropriateness as well.
