What language would be the most helpful to learn for someone who wants to go into the International Development Sphere?

I want to apply to a language internship where I do an immersive language program and am having trouble choosing a language. There isn't really one that stands out to me, I just really want to be sure I choose a language that will be helpful in my future aspirations. I do not fully know what I want to do when I graduate, I am currently a 3rd year at UCLA, but my major is International Development. I definitely want to work in that area or maybe the state department? I am just not sure what languages would be helpful or that are used a lot abroad/ are well known. Thank you so much!
