Chelsea owner Roman Abramovich has participated in peace talks between Ukraine and Russia.
"I can confirm Roman Abramovich was contacted by the Ukrainian side for support in achieving a peaceful resolution, and that he has been trying to help ever since," a spokeswoman for Abramovich said. "Considering what is at stake, we would ask for understanding as to why we have not commented on either the situation as such or his involvement."
Russian President Vladimir Putin ordered an invasion of Ukraine last week and has received worldwide condemnation. The two countries have been at war on Ukrainian territory ever since, with 352 civilians, including 14 children, having died as of Sunday, according to the Ukrainian health ministry.
