How do I market my paintings internationally?

I’m an internationally published artist living in the UK. My publisher is in Canada. They market a collection of my paintings as open edition prints worldwide. Also images of my paintings are translated into tapestries, tiles and granite panels through their licensing to companies in the US and Canada. An image of one of my paintings received bestseller status on their list. However my publisher does not deal with original paintings. I know I have a mive potential international market for my originals but have been relying on a local gallery only for sales of originals. How do I move my original paintings out internationally?
