The Czech Republic has not seen any signs that natural gas flows from Russia to Europe might be halted due to the conflict in eastern Ukraine, Czech Industry and Trade Minster Jan Mladek said in a statement on Tuesday. Mladek said he was satisfied that RWE Gas Storage, whose facilities account for 92 percent of Czech storage capacity, has used the summer months to fill its reserves to full capacity of 2.7 billion cubic metres.
