それに「cooperating」より「working together with」のほうがいいと思います。

We should be able to solve this problem in the near future
When you want to explain that you think a certain problem will have solution in the future; then you may explain this in the following ways:
-I think we will be able to solve this problem in the near future
-We should be able to solve this problem in the near future
特定の問題について「将来解決できるだろう」と説明したいなら、次のように言えます。
-I think we will be able to solve this problem in the near future（この問題は近い将来解決できると思う）
-We should be able to solve this problem in the near future（この問題は近い将来解決できるはずです）
We should be able to solve this problem eventually.
If you want to explain that you will most likely be able to solve this problem in the near future, you can say:
"We should be able to solve this problem eventually."
The word "should" indicates that it will most likely be solved.
「この問題はたぶん近い将来解決できる」は次のように言えます。
"We should be able to solve this problem eventually."（いずれこの問題は解決できるでしょう）
"should" は、それが「おそらく」解決されることを表します。
We should be able to resolve this issue very soon.
We can deal with this problem pretty quickly.
There are two ideas in all of my responses.
The first is that the problem can be taken care of. I use three verbs to accomplish this. They are "solve", "resolve" and "deal with". All of these words are the same in the idea that they express.
The other idea is that this problem will be resolved in a short amount of time. I use three phrases for this. They are "shortly", "very soon" and "pretty quickly".
