cheated by a chinese broker

Hi, My name is *****. I am the owner of ****** and do business in China since 2013. Recently I was working with a broker to help seek venders for certain parts. Via email the broker informed me that I needed to wire the money directly to the vender instead of the broker. Now when I am expecting to be receiving the products I purchased, The broker is claiming they were hacked. Me and my team are now out $100,000. I want to know what the best step should be. Thank you
