Trading with an empire will increase their opinion of you if the agreement is favorable for them. 

*On the left side of the trade interface, you can choose what to give to the other empire. You can give {{iconify|energy}}, {{iconify|minerals}}, {{iconify|food}}, {{iconify|Consumer goods}}, {{iconify|Alloys}}, border access, star charts, sensor access, strategic resources, star systems and other things.

*On the right, you can choose things to ask for. You can ask for more or less the same things, however, you cannot ask for star systems. Also, if you are giving or asking for monthly resources, sensor links, and/or strategic resources, you can choose how long the deal will last.

*In the center, you can see the other empire's willingness to accept the deal. They will accept if the number is positive and will reject with a negative number. Also in the center, you can change the deal length with a slider. You can also view what you are asking for and what you will give. Here, you can also change the amount of resources you are offering.

A good thing to know is that [[fallen empires]] will never be willing to give research agreements and will be overall less willing to trade.
