Thailand was dedicated for the preaching of the gospel on November 2, 1966, by Elder Gordon B. Hinckley. The first missionaries did not arrive until February 2, 1968.
Here is what President Chaichana had to say regarding this event:
We plan to have all members from all units gather together in Bangkok on November 12, 2016 to celebrate 50th Anniversary for the whole day. We will rent the national stadium or national convention hall for 4000 people. There will be exhibition booths for all church departments and each ward and branch from all over the country will display their unit's history. We will also have the local Thai food festival that everyone can test the local Thai food from every region. At night we will have culture and art showcase from the representatives of each part in Thailand.
The next day, November 13 we will hold the national conference which will preside by the general authority.
November14-15 is the annual Loy Kratong Festival
A couple days before that we plan to have fundraising activities for charity between members and RMs such as golf tournament, bowling tournament and a marathon.Suchat Chaichana
