A group of Latin American countries signed a resolution on Tuesday urging Venezuela President Nicolas Maduro to accept humanitarian aid to "alleviate" the country's migration crisis.
Hundreds of thousands of people have fled an economic collapse in Venezuela that has resulted in food and medicine shortages as well as failing public services.
Following two days of meetings hosted by Ecuador, the signatories called for "the creation of a humanitarian assistance mechanism that will allow the critical situation to be alleviated" and would target "the source" of "affected citizens." The group also called on Venezuela to "accept the cooperation of governments in the region and international organizations" to care for the communities of their nations living there.
Of the 13 countries meeting in Quito, only Venezuela's left-wing ally Bolivia refused to sign the document, while the Dominican Republic was unable to do so immediately for administrative reasons.
According to the United Nations, some 1.6 million people have left Venezuela since 2015.
The country is suffering a fourth year of recession, while the International Monetary Fund says inflation will reach one million percent this year.
