Alexei Miller, chief executive of Russia’s Gazprom, the world’s biggest gas company, and Oleh Dubyna, his counterpart at Ukraine’s Naftogaz, held talks late on Wednesday night ahead of the emergency meeting in Brussels on Thursday called by the European Union in a bid to end disruption to the EU’s supplies.

The two met in Moscow for their first face-to-face negotiations since the energy dispute erupted on January 1. A Naftogaz spokesperson told the FT an agreement had ”not yet” been reached.
