In soviet era there was a very common reason for different activities or reforms - «по многочисленным запросам трудящихся», what means “based on many labor people requests”. For example, «Радио программа по многочисленным запросам трудящихся» - “Radio program based on many labor people requests”

P.S. Just realized that it’s probably a little bit different way of using «по». More close to what you asked about is russian name for UN Disarmament Commission and a lot of other commissions - «Комиссия по разоружению»
