Following Tashi’s successful first flight at Lorraine Mondial Air Ballons, it was subsequently announced at a press conference that the Chinese authorities had attempted to prevent the flight from taking place.
According to event organiser Philippe Buron-Pilatre, officials from the Chinese consulate had protested against the appearance of the Tibet balloon claiming that it would undermine relations between France and China if the balloon was allowed to fly. Noting that the event is not political in nature, and acknowledging that the balloon is simply a representation of the Tibetan national flag and does not carry any derogatory slogan or political message, the organisers insisted that Tashi was free to fly.
