Russia's Novak declines to comment on diesel exports, citing commercial secrecy

MOSCOW, Oct 15 (Reuters) — Russian Deputy Prime Minister Alexander Novak on Thursday declined to comment on whether Russia has restarted exports of diesel, saying the issue was a commercial secret. US President Donald Trump said last Friday that he and Russia's Vladimir Putin had agreed that Russia would immediately release supplies of diesel to US and global markets in order to bring the price down.
