I want to know the answer to the following question:
When did the torch arrive in Vietnam?
All the background I'm provided with is that "However to sustain its relationship with China the Vietnamese government has actively sought to head off protests during the torch relay, with Prime Minister Nguyễn Tấn Dũng warning government agencies that "hostile forces" may try to disrupt the torch relay.". Is that enough to answer the question?
Answer: no
