Are different cultures more prone to closer friendships?

I got into a discussion with a friend who stated that she thinks people in wester cultures like the US would not sacrifice as much for their friends and don't have as tight knit bonds.  There is a lot to unpack here, like how to operationalize "closer" or "friendship", but I was wondering if there has been any research or frameworks on the subject.

There are cultural differences between the nature of friendship and the characteristics sought by friends from each other.

Gonzalez and colleagues (2004) compared Canadian and Cuban friendships. Cubans are more likely to focus on giving and receiving help, and character admiration. Canadians are more likely to focus on common interests and shared history. 

They concluded that these different types of friendship reflect the dominant ideals of the societies in which they're based (individualistic/pluralistic).
