Playing as the Maratha Confederacy I have taken all of India, and half of the middle east. This means I have hundreds of chests of spices, tea and cotton that are just building up. However, no matter how generous of an offer I make no one will trade with me. I offer all of my technology, one of my regions, thousands in coin and still they say, "Our two nations cannot trade because trade implies some kind of equality of worth."

Why? And how can I fix it?
