Concern is also running high over the impact that tit-for-tat sanctions between Moscow and Brussels over the Ukraine crisis could have on this tiny Baltic state, which is heavily reliant on trade with Russia.

Is that an expression? I tried to find the meaning of that phrase by doing a Google search but I really came up with nothing.

Answer 1

The expression used here is

to have (an) impact on someone/something

but it has been split up in your example. See also http://www.merriam-webster.com/dictionary/impact?show=0&t=1412527328, under "intransitive verb".
