An American student from Princeton University was arrested in Iran and has been sentenced to 10 years in prison on charges he was spying for the United States, an Iranian judiciary official said on Sunday, an action bound to aggravate relations between the two countries.

The arrest and sentencing of the American, Xiyue Wang, a graduate student in history, was announced months after he had vanished in Iran, where he was doing research for a doctoral thesis. There had been rumors of his arrest, but the announcement on Sunday from Iran was the first official confirmation.

A spokesman for Iran’s judiciary, Gholam Hossein Mohseni-Ejei, said at a weekly news conference that one of “America’s infiltrators” had been prosecuted, but he did not identify Mr. Wang by name or nationality. The judiciary’s Mizan News Agency provided his name and his age, 37, saying he had “spider connections” with American and British intelligence agencies.

Mizan also said Mr. Wang, whom it described as fluent in Persian, had digitally archived 4,500 pages of Iranian documents and had done “super confidential research for the U.S. Department of State, Harvard Kennedy School and British Institute of Persian Studies.”

A Princeton spokesman, Daniel Day, confirmed that Mr. Wang, an American citizen of Chinese descent, was the man arrested in Iran. “That’s our student,” Mr. Day said in a telephone interview.

He also said the university had known about the arrest for months but had been trying to work quietly to have Mr. Wang freed.

In a statement issued after news of his arrest and sentence was reported, the university said Mr. Wang was a fourth-year doctoral candidate specializing in 19th- and early-20th-century Eurasian history who had been arrested last summer while doing scholarly research in Iran on the Qajar dynasty.

“Since his arrest, the university has worked with Mr. Wang’s family, the U.S. government, private counsel and others to facilitate his release,” the statement said.

“We were very distressed by the charges brought against him in connection with his scholarly activities, and by his subsequent conviction and sentence,” the statement continued. “His family and the university are distressed at his continued imprisonment and are hopeful that he will be released after his case is heard by the appellate authorities in Tehran.”

News of Mr. Wang’s sentencing came as the judiciary spokesman also announced that the brother of President Hassan Rouhani of Iran had been arrested in a corruption inquiry, in what appeared to be a move by Mr. Rouhani’s hard-line rivals to undermine and embarrass him.

The brother, Hossein Fereydoun, had been one of Mr. Rouhani’s close aides.

The arrests suggested ominous new pressure on Mr. Rouhani, a moderate cleric who was re-elected to a second four-year term a few months ago.

His re-election was seen as a referendum vote by Iranians for more cooperation with other nations, including the United States, despite the entrenched anti-American hostilities harbored by other powerful interests in Iran, including its supreme leader, Ayatollah Ali Khamenei; the judiciary and intelligence services; and the Islamic Revolutionary Guards Corps paramilitary force.

The news of the arrests coincided with the second anniversary of Mr. Rouhani’s signature achievement: the agreement with the United States and other world powers to curb Iran’s nuclear activities in return for the easing of economic sanctions that have long isolated Iran.

The agreement has not produced the desired economic boom in Iran, giving political ammunition to conservatives who opposed the pact. Critics of the agreement in the United States have also complained, saying it is too weak.
