Last week, the president of Peru announced she was withdrawing her country’s ambassador from Mexico. The move comes after Peru also expelled the Mexican ambassador there late last year.

Peru’s President Dina Boluarte announced the ambassador’s removal after Mexican President Andrés Manuel López Obrador once again criticized her government on Friday.

He said that Boluarte has a low approval rating and that members of parliament are even less popular.

A supporter of her predecessor, he has repeatedly questioned the validity of Boluarte’s presidency. She took office in December after then-president Pedro Castillo was ousted and jailed for saying he would dissolve Congress before it could vote to impeach him.

Mexico’s foreign ministry has said that, despite the Peruvian ambassador’s withdrawal, Mexico will keep lines of communication open and that its diplomats and consular staff will stay in Peru.

López Obrador has been a vocal supporter of Castillo, whose wife and two children arrived in Mexico in late December and were offered political asylum just a day after Mexican Ambassador to Peru Pedro Monroy had been declared persona non grata and was given 72 hours to leave the country. Peruvian officials said he was being expelled because Mexican leaders were making comments that interfere with Peru’s internal affairs.

Peru has faced months of protests since Castillo's was removed from office. At least 60 people have been killed in the protests.
