Russia takes new steps to isolate Ukraine and faces budget pressure

Russia is taking new actions to economically isolate Ukraine. The country's rail chief said Russia aims to 'cut' entire regions from Ukraine's train network, and it plans to ban ships that visit Ukrainian ports from using its own Black Sea terminals.

Separately, reports indicate Russia is facing financial pressure. The KSE Institute says Russia is meeting its budget targets through spending cuts as oil prices slide, and a German intelligence analysis suggests Moscow's actual military spending is higher than what has been publicly stated.
