(CNN) - Activist Chen Guangcheng, his wife and two children arrived Saturday evening in the United States, bringing an end to a diplomatic kerfuffle that erupted after he escaped from house arrest and took to YouTube to complain about abuse he said his family suffered at the hands of Chinese authorities.
United Airlines Flight 88 landed at New York/Newark Liberty International Airport to little fanfare after the U.S. State Department prohibited public and media access.
Reporters traveling with him were denied access to Chen for much of the 13-hour flight until he agreed to talk to one member of the media.
Chen expressed mixed feelings about arriving in the United States, saying he has unfinished business at home, according to CNN's Steven Jiang, who was on board the flight.
Chen, 40, is due to begin a new chapter in his life as a student at New York University after China had said that he could apply to study abroad.
Chinese-speaking diplomats from the U.S. Embassy in Beijing traveled with the family, according to two senior State Department officials.
Chen had neither passport nor visa in hand when he was shuttled to the Beijing airport for the flight. At the airport, Chen waited with his wife and two children in a secure location. He was in a wheelchair, dark glasses over his eyes -- Chen is blind.
Chen had been in a Chinese hospital for the past few weeks, awaiting documents to travel after New York University offered him a fellowship.
As the wheels lifted off Chinese soil, so, too, did the anxiety that has enveloped Chen and his family over a past of mistreatment and a future of uncertainty.
The self-taught legal activist angered Chinese officials with his fight against alleged forced abortions under China's one-child policy.
Chen spent four years in prison, and was then held under constant lockdown in his village.
New York University law professor Jerome Cohen, who first met Chen when the activist traveled to the United States as part of a State Department program in 2004, said he was "very happy" to hear the news of Chen's pending arrival in America.
Bob Fu, president of ChinaAid, a Texas-based Christian human rights organization that has been campaigning for Chen's freedom, said the activist was deeply grateful to the international community's efforts to secure his freedom -- efforts that tested U.S. relations with the Communist giant.
Chen spent six days in the U.S. Embassy after he escaped house arrest in April ahead of a visit to Beijing by U.S. Secretary of State Hillary Clinton.
The one thing Chen could not leave behind was fear of reprisals for the rest of his extended family at the hands of the authorities in Shandong Province in eastern China.
"My elder brother was taken away by these thugs without any reasoning and then they came back and started beating up my nephew, and they used stakes and violently beat him up," Chen told the House Foreign Affairs Committee in a telephone call from his hospital room earlier this week.
Chen added that his relatives' homes had been broken into and they had been beaten by people working for the government.
Chen said his nephew Chen Kegui tried to defend himself and now faces a "totally trumped-up" charge of attempted homicide. "After my nephew was beaten up, he actually was waiting to surrender himself and the police come back again and violently beat up my sister-in-law," Chen said.
The authorities in Linyi, the city that oversees Chen's village, had issued a statement accusing Chen Kegui of injuring government officials with a knife and saying he would be dealt with according to the law. They have declined to comment on the matter since.
ChinaAid urged the international community to continue to monitor the situation for Chen's extended family in China, amid concerns over possible reprisals by the authorities.
Amnesty International echoed that concern.
"Chen's journey to the United States would not have been possible without his own valiant character, the courageous support of his family and friends and the robust voice of the international community that never stopped working on his behalf," said Frank Jannuzi, head of Amnesty International's Washington office.
"But while Chen and his immediate family are safe, Amnesty International continues to be concerned about those in China who share his quest for justice, for they remain in serious jeopardy," he said. "Countless people, known and unknown, are subject to arbitrary detention, beatings and other forms of repression.
For Chen, whose escape from authorities in Shandong played out like a Hollywood thriller -- a persecuted blind man who climbed over a high wall and hid in a pig sty -- Saturday's sudden journey over an ocean and a continent was perhaps a fitting chapter in his story.
Sunday morning, Chen will begin a new life in America, calm and resolute as always.
"You got the feeling you were in the presence of some Chinese equivalent of Gandhi or something," Cohen said. "He had this gentle but steely moral force."
Chen never sought out to be a rabble-rouser, Cohen said, though he will always be thought of as one.
