where he had fled? Does "where" here refer to "Beijing"?

Or refer to "the United States Embassy (in Beijing)"?

Context:

From my experience, one can see how the Communist Party operates — why it makes promises and what its so-called guarantees mean. It is obvious that Mr. Chen did not understand the emptiness of these promises, which explains why he initially accepted the government’s pledges and left the United States Embassy in Beijing, where he had fled after escaping house arrest in his village, for treatment at a hospital. (On Friday, a tentative agreement that would allow Mr. Chen to travel to the United States as a student was announced.)

Link deleted. The article to which the link took us have political background. Forum rules state, "This is a forum about the English language, so please do not post topics on politics or religion. If you wish to discuss politics or religion there are many other sites which are dedicated to these topics." Passages about religion/politics are acceptable so long as the only question is one of language usage - which is why the question above has not been deleted. I hope you understand. 5jj

It is not possible to say for certain.

I guess it refers to "where he had fled to" - Chen fled to Beijing after escaping his house arrest.

He had fled to the US Embassy, in Beijing.

But you need to know this.
The sentence, on its own, could simply mean that he fled to Beijing right away, stayed there for a long time, and then went to the Embassy. There is nothing in the sentence that tells you for sure that he fled to the Embassy.
