Move comes after Betssy Chavez, who is on trial on coup charges, fled to the Mexican Embassy in Peru.

Peru has severed diplomatic relations with Mexico after accusing it of granting asylum to a former Peruvian prime minister who is on trial over an alleged coup attempt in 2022.

The announcement on Monday came hours after former Prime Minister Betssy Chavez – who served under former President Pedro Castillo – fled to the Mexican Embassy in Peru.

“Today we learned with surprise and deep regret that Betssy Chavez, the alleged co-author of the coup attempt by former President Pedro Castillo, is being granted asylum at the Mexican Embassy residence in Peru,” Minister of Foreign Affairs Hugo de Zela told a news conference.

“Given this unfriendly act, and considering the repeated instances in which the current and former presidents of that country have interfered in Peru’s internal affairs, the Peruvian government has decided to sever diplomatic relations with Mexico today,” he added.

There was no immediate comment from Mexico.

Chavez’s lawyer, Raul Noblecilla, told local radio station RPP that he had not heard from his client in several days and was unaware of whether she had requested asylum.

Chavez, who served in Castillo’s cabinet as Minister of Culture, was appointed as prime minister in November 2022 amid a months-long standoff between the president and the Congress.

Castillo – a former rural schoolteacher and trade unionist, dubbed Peru’s “first poor president” – was impeached by lawmakers the following month when he attempted to dissolve the Congress.

Relations between Lima and Mexico deteriorated sharply afterwards.

Following his impeachment, Castillo was on his way to the Mexican embassy in Lima to request asylum when he was arrested and charged with rebellion and abuse of authority.

Chavez was charged alongside him.

In December 2022, Peru expelled Mexico’s ambassador after Mexico granted asylum to Castillo’s wife and children.

Castillo’s successor, then-President Dina Boluarte, also temporarily recalled Peru’s ambassador to Mexico City in February 2023, accusing then-left-wing president Andres Manuel Lopez Obrador of meddling in her country’s affairs for expressing support for Castillo.

The former president and Chavez went on trial in March of this year.

While Castillo has been in preventive custody since his impeachment, Chavez was released on bail in September.

Prosecutors had sought a 25-year term for Chavez for allegedly participating in Castillo’s plan to dissolve Congress.

They have sought a 34-year sentence for Castillo.

The pair has denied the charges.
