The Chinese know very well that they cannot handle questions on their recent claim that "Tawang of Arunachal Pradesh is that of China" when it is established beyond doubt that it belongs to India. They also know that they can hardly handle burning issues about their octopus grip on Tibet.
That is why they requested the Government of India to ensure that no questions from the media is allowed!!!!
The Chinese know to bully and Indian authorities only know to ridicule itself!
