Nepalese leaders say they will uphold the country's "One China" policy, making sure Nepal's territory is never used against its neighbor.
Nepalese officials made the pledge during a visit to the Himalayan country by China's Foreign Minister Yang Jiechi.
Yang on Wednesday said he appreciated Nepal's efforts to crack down on massive protests by Tibetan exiles, before and during this year's Olympic games.
During his visit, Yang met with his Nepalese counterpart and Nepal's Prime Minister Pushpa Kamal Dahal.
Yang also pledged 15-million dollars in development aid to Nepal, and said China would work with Nepal to improve the country's infrastructure and boost tourism.
Nepal is home to about 20-thousand Tibetans who fled their homeland after a failed uprising against Chinese rule in 1959. The country recognizes Tibet as part of China.
