Can I travel on a tourist L type to collect a business award on behalf of my employer.

The awarding body is hosting the awards ceremony at the Hyatt Bund hotel in Shanghai.
I will be travelling on the 21st September 2016 and returning on the 24th September 2016.
No business activities will be completed only the attendance at the ceremony and the collection of the award on stage.
Do I need an invitation letter from the awarding body for the event for my visa?
Thank you
