The Russian ambassador to Washington says the United States has prolonged the war in Ukraine to profit from its sales of military equipment and liquefied natural gas (LNG) to European countries.

France's finance minister has warned that the United States should not be allowed to dominate the global energy market while the EU suffers from the consequences of the ongoing conflict in Ukraine.

The European Union turns to the United States to deal with its worsening energy crisis, making the US the biggest profiteer, experts say.
