The Brazilian government rejected an offer of aid by the G7 countries in ending the Amazon fires, according to AFP.
"We appreciate [the offer], but maybe those resources are more relevant to reforest Europe," Onyx Lorenzoni, chief of staff to President Jair Bolsonaro, told the G1 news website, as cited by AFP.
On Monday, Macron announced that the G7 would "immediately send to the Amazon countries [...] financial support worth at least about 20 million euros."
The Amazon rainforest, which produces about 20 percent of the Earth's atmospheric oxygen, is burning from wildfires at a record rate and has drawn international attention.
Environmental activists have staged protests at Brazilian embassies worldwide and accuse Brazilian President Jair Bolsonaro of supporting farmers who are burning the rainforest to expand farming land.
On Saturday, Brazilian authorities deployed troops in an attempt to fight the ongoing environmental disaster.
