I am Indian Citizen; can I get visa to China if Authorisation letter from Beijing issued? Alam

I am an Indian passport holder travelling to Nepal as IFAD Consultant. From there I am required to travel to China (Qinghai province) also as IFAD consultant. As I do not have time to tavel back to India, I am requesting authourities in Beijing to send the letter of V authorisation to China to the Embassy in Nepal. In that case would I be considered for issuing one given all documents are in order. I have been to China before for similar purpose. Please clarify
