KYIV: A senior Kremlin official said Friday that Russian police and National Guard will stay on in eastern Ukraine’s Donbas and oversee the industry-rich region, even if a peace settlement ends Russia’s nearly four-year war in Ukraine. The remarks by Kremlin adviser Yuri Ushakov underscore Moscow’s ambition to maintain its presence in Donbas post-war. Ukraine is likely to reject such a stance as US-led negotiations drag on.
