The main reason, according to sources from Kommersant, is that the cost of electricity exports from Russia has increased and now exceeds domestic prices for this resource in China. As a result, continuing purchases has become economically unfeasible for the Chinese side.
Analysts interviewed by the newspaper point out that the volumes of electricity supplies from Russia to China were relatively small compared to domestic production in the PRC, which allows the Chinese energy system to easily compensate for these volumes.
