WARSAW, Poland (AP) — Poland has signed a long-term deal with a U.S. company for supplies of liquefied natural gas as part of an effort to reduce its dependence on Russian energy.

Port Arthur LNG, a subsidiary of Sempra Energy, and Poland's state gas company PGNiG issued a joint statement Wednesday announcing the agreement for the sale of 2.7 billion cubic meters per year of gas to Poland over a 20-year period.

The statement said that is enough to meet about 15 percent of Poland's daily gas needs.

Sempra Energy's CEO Jeffrey Martin said the deal helps his company "advance our vision to become North America's premier energy infrastructure company."

No financial details were disclosed.

In recent weeks Poland also signed deals for gas with American suppliers Cheniere and Venture Global Calcasieu Pass and Venture Global Plaquemines LNG.
