Sometimes people don't want to give up all of their money for some oil maybe they want to throw in a province or two instead. Sometimes province trading is not equal and you wish you could add in some resources but you cant. You must be able to provide a more diverse trade.
Also offer technology trading, able to spread their power faster with allies (keeps the importance of allies).
Counter offers should be made capable, so that if you only want to tweak their offer you can do so without creating a whole new trade.
Also if their could be some way to pay a country to do something for you that could be nice too, but there would have to be a way to ensure their doing what was asked, possibly a newspaper article at headlines with the rest of the player articles. Or maybe the payment is made after the offer is completed, for example:
Colombia offers to pay Argentina 4,000 dollars to attack a specific province in Chile, and once that province has been taken the payment is fulfilled, and 4,000 dollars is given to Argentina. Or perhaps Germany wants the UK to attack northern islands of Denmark, to give to Germany, the province is given to Germany after occupation, and if they are not allies, then it will wait for the UK to exit the province, then it will be given to Germany and the payment is made.
If these things can be added, it would greatly help the game improve in diplomatic activity.
