Zhou [1]:
Please pay attention to the timing of the attack on Changdu [2]. Consider having an appropriate person from the Ministry of Foreign Affairs disclose to the Indian ambassador that it is hoped the Tibetan delegation will arrive in Beijing for negotiations by mid-September. Our army is about to advance into Tibet. If the Tibetan delegation is sincere, they should come quickly, and it is hoped that the Indian government will provide possible assistance for the delegation's travel.
