Have the Spanish boys gone too far?

Spanish basketball team poses for offensive picture, slanting their eyes for La Marca.
Spain's Olympic basketball team really went too far this time, didn't they?
Do they really have to do that? They are guests of the Chinese people, they compete in their country and participating in their venues. To pose for an advertisement prior to the Games which appears to show all its players slanting their eyes, is 100%a move that is not only offensive but rude.
