On the sidelines of a NATO meeting in Romania, the United States is expected to announce "significant" financial aid to Ukraine to help it deal with the damage Russia has inflicted on its energy infrastructure, senior American officials announced.

The aid, which will be presented in detail by Secretary of State Anthony Blinken, will be substantial and will not be final, a high-ranking US official told reporters, who did not want to be named or to reveal the intended amount or other details.

However, he pointed out that the administration of President Joseph Biden has set aside $1,1 billion from the energy budget for Ukraine and Moldova. That aid was announced for an international conference of creditors in support of Ukraine's civil resistance scheduled for December 13 in France.

In early October, Russia launched a major campaign of missile attacks targeting energy infrastructure across Ukraine. According to data provided by the Ukrainian Government, between 25 and 30 percent of the country's energy infrastructure was damaged in the attacks.

"What the Russians are doing is attacking high-voltage transformers, not just power plants, in order to disrupt the entire process - from production to distribution," said an American official.

NATO foreign ministers are meeting today and tomorrow in Bucharest, and one of the main topics of the meeting will be the Alliance's support for Ukraine since the beginning of the Russian invasion on February 24. a
