Is the Spanish (es) the same international Spanish used by the UN?

Hi, I asked a question and got a response but it didn't answer my question - but as its been marked answered so I don't know if anyone will get back to my reply to his response. Sooooo I'm starting a new question...

You have there are two Spanish languages available on your site. Spanish (es) and Latin American Spanish (es-LA) - we're not thinking about Mexico Spanish at this point. We would like to know if the Spanish (es) is the Spanish spoken in Spain or is an international version of Spanish used by the international organisations such as the UN, which is a combination of Spanish (es) and Latin American Spanish (es-LA). Could you confirm asap please.

Thank you, Suzi
