Venezuelan opposition envoy Maria Teresa Belandria was received as her country's official ambassador in Brazil on Monday and said Brazil's government would provide all possible support to get humanitarian aid to the border.
"We Venezuelans shall return to the streets ... to demand the entry of humanitarian aid which will save the lives of more than 300,000 Venezuelans now at risk of dying", Guaido tweeted late Monday.
The U.S. humanitarian aid is being stored in a warehouse across a river from the socialist rally, a situation that also puts Maduro in a tight situation, said Eric Farnsworth of the Council of the Americas and Americas Society, a Washington-based think tank.
Several tons of medicine, food and basic items have been stocked since Thursday in Cucuta, close to the border crossing point of Tienditas which Venezuelan soldiers have blocked with freight containers.
Venezuela is in the midst of a disastrous economic crisis marked by hyperinflation, recession and dire shortages of food and medicines.

Beto O'Rourke is holding a rally in El Paso, Texas , on Monday night, in direct competition with President Trump's own event. Mr Trump said he had heard about progress in the talks just before he took the stage, but he also did not discuss details.
Maduro has said that Guaido is trying to set up "a puppet government" in Venezuela.
"It's unfortunate that Europe, after being kicked by Donald Trump, are now behind Donald Trump", Maduro said of the European countries which contest his presidency.
Lester Toledo, head of Guaido's aid distribution team, told reporters that the Roraima center would start receiving supplies next week.
Before the beginning of the exercises, the president arrived in the northern state of Miranda to take a look at the military equipment, including Russian-built rocket launchers that are used by the Venezuelan Armed Forces. Maduro called the American sanctions the reason behind Venezuela's economic problems that in this way the U.S. "has meant to create a humanitarian crisis in order to justify a military intervention".
The militia is a civilian force founded in 2008 to supplement the armed forces.

Juan Guaidó is touring Venezuela this week, meeting with journalists and citizens. Guaido has formerly said he may "authorize" USA military intervention in the country.
"There are people responsible for this and the regime should know it", Guaido said after attending Sunday mass with his wife and 20-month-old baby. We do not now have any electoral mechanism that works because everything has been tarnished by fraud.
"Why do we protect the assets of Venezuela?" "It's help for many Venezuelans like my son".
Pope Francis has said he would be prepared to mediate between the rival leaders but Guaido has rejected negotiations with Maduro, believing he would use them to buy time.
Mr Guaido called the move "almost genocidal".
