I offer you my best wishes and support in this regard. Thailand and the United States share a long history of friendship and cordial relations stretching back 183 years. Thailand is the first ally of the United States in Asia and our alliance has formed a bedrock of peace, stability and prosperity of the Asia-Pacific. Our long standing ties are preserved and propelled by mutual interests in various areas, including economic, security, social and regional cooperation.  We stood together and fought shoulder to shoulder in the past. The bonds of friendship between our peoples have always been strong and enduring. I truly believe that the relationship between Thailand and the United States will be strengthened under your leadership.  I look forward to working closely with you and Vice President-elect Pence to reinvigorate the mutually beneficial relationship between our two countries and peoples, and advance the strategic partnership between ASEAN and the United States. I wish you every success in your endeavors. Yours sincerely, General Prayut Chan-o-cha (Ret.) Prime Minister of the Kingdom of Thailand
