Italy hasn't suffered any negative reaction from U.S. authorities after having agreed to be part of China's Belt and Road initiative, the country's finance minister told CNBC Friday.

Rome was the first major G-7 economy to sign a memorandum of understanding (MOU) with Beijing to be part of its massive infrastructure plan — a move that has raised eyebrows in the United States and in some other European countries.

However, Giovanni Tria, an economist in charge of Italy's finances, said: "We have not (had) any backlash."

"We have a strategic partnership, an alliance with the United States and the other countries allied in NATO and this doesn't change," he told CNBC's Joummana Bercetche at the IMF's Spring Meetings in Washington, D.C.
