"Many are talking about a break in diplomatic relations with the Russian Federation. But no one is explaining how this would help us reach the goals that have been set," Klimkin said in an interview with the Zerkalo Nedeli (Mirror of the Week) newspaper.
Russia and Ukraine have been at loggerheads since the outbreak of violence between Kiev forces and its eastern regions of Donetsk and Luhansk last year.
"If diplomatic relations are severed, then negotiations will be held exclusively through intermediaries. I doubt that a situation when the issue "about us" will be solved "without us" would be the best bet," Klimkin said.
Tensions in Ukraine escalated to a state of armed confrontation in April 2014 when Kiev made a decision to launch a military operation in the country's southeastern regions, attempting to suppress the pro-independence fighters of Donbas.
Kiev, alongside Western nations, has accused the Russian government of backing the independence supporters and sending its troops to assist them in the fight against Ukrainian forces, alienating itself from Moscow. However, Russia has denied the allegations and repeatedly made calls for a peaceful settlement of the crisis.
