Given this paragraph about Nicaraguan nationality law, with which countries can Nicaraguan citizens obtain dual citizenship?

Context: Nicaragua has a large diaspora that make significant contributions to the economy. Recognizing that forcing them to give up Nicaraguan nationality to acquire a different nationality would impact the country, changes were made to eliminate the possibility that birthright Nicaraguans could lose their nationality. Nicaragua has dual nationality treaties with Argentina, the nations of Central America, Italy and Spain. Children born abroad who obtain nationality by birth in another place are also accepted as dual nationals. In the case that their parents are naturalized Nicaraguans, they must ratify their choice of Nicaraguan citizenship upon attaining the age of 16.

Answer: Nicaraguan nationals can obtain dual citizenship through joint-treaty with Argentina, Central American nations, Italy, and Spain. Children with parents who are Nicaraguan citizens that are born abroad will receive dual citizenship.
