Finland's United Nations representative defended the country's health care on Wednesday after Nikki Haley appeared to knock the Finnish system in a string of tweets.

It all started after Haley, the U.S.'s former U.N. ambassador, dug up a weeks-old tweet from Vermont Sen. Bernie Sanders, an Independent seeking the Democratic nomination for president in 2020.

On March 6, Sanders tweeted that it costs "on average, $12,000" to have a baby in the United States.

"In Finland it costs $60," he added, before injecting part of his campaign platform. "We've got to end the disgrace of our profit-driven health care system and pass Medicare for all."

Haley retweeted the tweet Wednesday with a critique of Sanders, telling the senator "you're not the woman having the baby so I wouldn’t be out there talking about skimping on a woman when it comes to childbirth. Trust me! Nice try though."

It's what she said next that would catch the attention of Kai Sauer, Finland's permanent representative to the U.N.

"Health care costs are too high that is true but comparing us to Finland is ridiculous. Ask them how their health care is. You won’t like their answer," she said.

A few hours later, Sauer responded in a series of tweets.

"Here are some facts: Finland has a high performing health system, with remarkable good quality in both primary and hospital care. The country also achieves good health status at relatively low level (sic) of health spending," he said.

He then moved to the debate that started it all: maternal care.

"Finland has the world's third lowest infant mortality rate," he said. "Maternal mortality is the lowest in the world in Finland." The country, he claimed, also has the second lowest total mortality from cancer of European Union countries. His short rant finished with a link to a news article naming Finland the happiest country in the world.

"Apologies for the delayed reply," he said, "but we were out celebrating our rank as the happiest country in the world."

The U.S. has the highest maternal death rate among the world's developed nations and it's been getting worse. Two women die in childbirth almost every day in the U.S., that's about 700 per year.
