Swedish Foreign Minister Margot Wallström called the news "very unfortunate" and said the ministry would seek an explanation from the Guatemalan government.
Maria Leissner is a former Swedish ambassador to Guatemala and member of the Liberal Party. She tells Radio Sweden that Guatemala's problem isn't with the current ambassador Anders Kompass, but rather Swedish policy.
Leissner says she thinks Guatemala is trying to discourage Sweden from backing an international commission that investigates official corruption and human rights violations in the country.
"This is not about one single person," says Leissner, who stressed she was speaking as an individual and former ambassador and not as an official voice from the Swedish foreign ministry.
