Were not eager? Yatseniuk as the prime minister signed it on February 21st 2014, less than a month after coming in power. Poroshenko signed the economic parts of it on June 27th, again less than a month after taking office.
No, he did not. He signed meaningless fluff. Important economic part had not been signed until late last year or something. And it was a bad deal but they had to sign it because there were no choice.
Basically Ukraine opens its market to EU, and get nothing in immediate return except tiny quotas on EU market for some of the stuff which they can actually sell. They had used these yearly quotas in a matter of weeks in 2016, they were so tiny. Meanwhile they lost Russian market. I remember EU critters begging Russia not to do that, but that could not be done because that would mean reexport EU stuff into Russia without tax.
People here say EU fucked Greece. Well, EU double fucked Ukraine.
