State Department officials are “disappointed” with a decision by UK prosecutors to charge a US diplomat’s wife in a wrong-way crash that killed a British teen, saying it won’t resolve the case.

Anne Sacoolas, 42, has been charged with causing death by dangerous driving in the crash that killed 19-year-old Harry Dunn in August, Britain’s Crown Prosecution Service announced Friday. She faces up to 14 years in prison if convicted.

British prosecutors said extradition proceedings against Sacoolas have already begun, but US officials poured water on the possibility of her returning to the UK to stand trial.

“We will continue to look for options for moving forward,” a State Department spokesman said in a statement. “We are disappointed by today’s announcement and fear that it will not bring a resolution closer.”

Families of diplomats are granted immunity from arrest or detention under the Vienna Convention on Diplomatic Relations, but prosecutors in Britain claim that doesn’t extend to dependents of consular officials who are based outside of London.

State Department officials have maintained, however, that Sacoolas — whose last known address is listed as Vienna, Virginia, phone records show — had conferred diplomatic immunities at the time of the fatal wreck near Royal Air Force Croughton in Northamptonshire.

“We do not believe that the UK’s charging decision is a helpful development,” the statement continued.

President Trump, Secretary of State Mike Pompeo and US Ambassador Woody Johnson have expressed their “sincere condolences” to Dunn’s family after his death, according to the State Department.

Sacoolas, the wife of US intelligence officer Jonathan Sacoolas, sparked outrage upon fleeing the UK on a private flight while claiming diplomatic immunity after her Volvo struck Dunn’s motorcycle on Aug. 27, killing him.

Sacoolas’ attorney, Amy Jeffress, said in a statement to The Post on Friday that the diplomat’s wife remains “devastated” by the “tragic accident” that killed Dunn — but doesn’t plan to willingly return to the UK to face prosecution.

“Anne would do whatever she could to bring Harry back,” the statement read. “She is a mother herself and cannot imagine the pain of the loss of a child. She has cooperated fully with the investigation and accepted responsibility.”

A State Department spokesperson, meanwhile, said the request by the UK to extradite Sacoolas is problematic.

“It is the position of the United States government that a request to extradite an individual under these circumstances would be an egregious abuse,” the spokesperson said in an email. “The use of an extradition treaty to attempt to return the spouse of a former diplomat by force would establish an extraordinarily troubling precedent.”
