If Russia agrees to a complete ceasefire on line of control, Ukraine would have no choice but to agree with it. Zelensky might be talking tough before the meeting but he is hoping a complete ceasefire would come in action.
Russia too have interest in a ceasefire as that may enable them to get back to world market. The war is about to ruin their economy. This might stop the Putin's dream of having a land border to Transnistria but Ukraine like always would still be up for grab anytime. One way or other.
If Putin plays his hand well, he might end up with a rind which gives land (aka, pipeline) access to Transnistria, Romania, Hungary, Slovakia, and Poland. This would give Russia immense power going forward. Not only that, but it could make some of the said happy to be whole states again West of Carpathias which could potentially even win them over to the SMO project after getting royally shit on by the drug-adled WEF pervs (France, Britain, Germany, etc) and their sponsors who are stuffing Eastern Europe full of migrants and turning their peeps sick and gay. Even Poland would be a winner to a degree by not having to pay Ukrainian gas transit fees if not chunks of what's left of the rump state.
Putin needs a dip-shit (or co-conspirator) like Zelensky in Ukraine for as long as possible, however, in order to have a chance to pull something like this off.
