Mexican President Andres Manuel Lopez Obrador is expected to ask U.S. President Joe Biden to share part of the Covid-19 vaccine supply on Monday, a Mexican government official said about plans for the conversation.
The two leaders are due to hold a virtual bilateral meeting on Monday.
The aspect of the collaboration (a purchase agreement, a donation or a loan) is not defined, the official told CNN.
The first step is to ask whether the United States is willing to cooperate, the source said.
Mexico has established purchase agreements for hundreds of millions of vaccine doses with different vaccine manufacturers around the world, the vast majority of which have not yet been met.
It has also purchased vaccine supplies in both Russia and China, but has not received any vaccine directly from the United States, its most important ally and largest trading partner.
Pfizer, an American company, has shipped Covid-19 vaccines to Mexico, but they were produced in European laboratories and have come with a relatively limited supply.
As of Sunday evening, Mexico reported having administered just under 2.5 million doses of coronavirus vaccines.
