Ukraine’s president on Saturday (31 August) slammed the controversial Nord Stream 2 pipeline set to send Russian gas to Germany as a “threat” to Europe and welcomed moves by Kyiv to tap into US gas supplies.

Volodymyr Zelenskiy made the comments beside Poland’s President Andrzej Duda in Warsaw, where he attended the ceremonies marking 80 years since the outbreak of World War II.

“We hold the same position as Poland: Nord Stream 2 is unacceptable and it threatens Europe as a whole,” Zelenskiy told reporters, according to Euractiv.com. “We want the diversification of sources of energy delivery within the US, Poland and Ukraine triangle,” he added.

The US, Poland and Ukraine agreed later on Saturday in Warsaw to beef up cooperation aimed at securing energy supplies in a region previously reliant on Russian deliveries.

The agreement is largely focused on gearing Ukraine’s gas infrastructure to deliveries from the West, including US liquefied natural gas (LNG).
