(CNN) The president of the Venezuelan National Assembly, Juan Guaidó, has claimed victory after the International Federation of Red Cross and Red Crescent Societies announced Friday it would have unhindered access to bring aid into the struggling country.

"The world knows it: this victory is thanks to the mobilization of the people of Venezuela ," Guaidó, who has been recognized as interim president by more than 50 nations, including the United States, tweeted shortly after the announcement.

Guaidó called the announcement a defeat for embattled President Nicolas Maduro and his government. Guaidó vowed his movement would continue while Maduro remained in power: "The dictator will want to disguise his defeat, but we continue firm in our route and will move forward until the end of the usurpation. That is the great task that befalls us all."

The Red Cross will have the "legal and technical conditions" to start humanitarian aid deliveries to Venezuela within a month, Red Cross President Francesco Rocca told reporters in Caracas.

Rocca said the goal of the Red Cross is to start delivering aid to 650,000 people within 20 days, and stressed that the delivery of aid will be a technical operation, not a political one.
