Does this not answer the question over Trade if we leave the EU?

In an interview with BBC business, the Chief Chinese Trade Delegate was asked if the possibility of the UK leaving the EU, would affect possible trade deals between the UK and China.

The delegate was very clear that there would be no difference at all, whether the UK was in or out.

We are about to get heavily involved with China, at the moment, we will have to register all trade via the EU under the Rotterdam agreement. The EU will take a piece of the pie, as they do in all our trade deals.

Surely we can now be certain that we can trade and make maximum profits away from the EU instead of being tied to it and paying it.
