The chair of the foreign affairs committee in the Ukrainian parliament, Oleksandr Merezhko, says the country has limits on how far it would go to accept peace with Russia.

Axar.az reports citing BBC.

"We have three very firm red lines when it comes to Ukraine," he tells the BBC, listing these as:

- Territorial integrity - "it's not negotiable. We will never agree to any territorial concessions"

- Ukraine’s membership in international organisations, in particular in Nato - "Putin shouldn't decide that"

- Defence capabilities - "We cannot agree to Putin's suggestions, some kind of limits on our defence capabilities"

Merezkho goes on to say that he doesn't know what President Trump expects from Russian leader Vladimir Putin, but adds "Putin has proved many times he's a pathological liar and manipulator".

Trump and Putin are expected to hold talks tomorrow. Ukraine has agreed to a 30-day ceasefire plan initiated by the US. Russia has said it supports the idea but added that there are "nuances" to be worked out.
