His Majesty King Bhumibol Adulyadej (Rama IX) has taken upon himself the daunting task of working for the well-being and livelihood of his subjects all over the country. Yet, as Head of State under the Constitution, he has numerous duties in forging friendly ties with various countries. In diplomatic protocol, he receives foreign ambassadors to Thailand, who officially present letters of credence to him upon their accreditation to Thailand and take leave at the completion of their terms. He also grants audiences to Thai ambassadors to various countries and gives them a royal blessing before they leave to take up their posts. He also made efforts to pay state visits to friendly countries when time permitted. And with the royal children grown up, they share the burden in reinforcing the bonds of friendship with various countries by paying royal visits to observe technical progress and promote cooperation with them, leading to good understanding and benefits to the country and the people, which is the true objective of the Royal Ties of Friendship, a time-honored mission of the Thai monarch.

Thanpuying Kenlong Snidvongs Na Ayudhya, a lady-in-waiting, related the state visits abroad between 1959 and 1967 in her book Tham Pen Dhamma (Doing Things the Dhamma Way):

Several countries extended formal invitations to Their Majesties the King and Queen. Therefore, His Majesty deemed it appropriate to embark on state visits with Her Majesty the Queen, as invited.

It was the first occasion for Their Majesties the King and Queen to have assumed the roles of the country’s representatives in the wide world, so that Thailand and her people could be appreciated for their fine culture, on a par with any of the world’s nations, a primary royal mission carried out by Their Majesties for the country....

During the state visits paid by Their Majesties the King and Queen to various countries, they were accorded full honors and a warm welcome with the greatest hospitality. They visited places of archeological and historical importance and experienced the glorious art and culture of ancient lands, the advances of the modern world filled with industrial plants, new agricultural practices, and technology, as well as peoples of various races and different perspectives, even the citizens of every country, who came out and cheered them wholeheartedly.

His Majesty’s deep thoughts on such extensive royal visits to foreign countries were revealed in this portion of his departure speech, delivered to the Thai people:

This foreign trip is in fact a state affair, part of the performance of my duties as the Head of State.

It is well known that these days, various countries, large and small, are interdependent. One may say that people of all nations are like relatives. Efforts must be made to know one another, and to reinforce the ties of friendship.

Normally, relatives exchange visits to show their mutual care and concern for one another. But in the case of countries, it is difficult for hundreds of thousands or millions of people to exchange visits. Therefore, it is the duty of the Head of State to visit various nations. I shall convey to the peoples of those countries the Thai people’s goodwill toward them, and I shall give my utmost effort to make Thailand known to them, and to create goodwill in them toward the Thai people.

After that prolonged foreign tour, His Majesty the King did not venture abroad again, until 28 years later in 1994, when he inaugurated the Thai-Lao Friendship Bridge and crossed over to visit the Lao People’s Democratic Republic.

And as His Majesty advanced in age, the Crown Prince, the Princesses, and other royals are actively sharing the burden of forging royal ties of friendship with the international community.

The first State Visit was to the Republic of Vietnam, 18-21 December 1959.

The State Visit to the Republic of Indonesia, 8-16 February 1960. His Majesty the King remarked in his speech at the state banquet hosted by President Sukarno: I believe that happy relations existing between our two countries will continue to grow in strength and should result in complete unity of purpose and in perfect understanding.

The State Visit to the Union of Burma, 2-5 March 1960. His Majesty the King made this response to the welcome address by the Burmese President U Win Maung: The Burmese and Thai peoples are bound together in friendship, through sharing the same Buddhist faith, as well as the same aspiration of peace and cooperation. I am therefore all the more happy in being able to bring to you the goodwill and the greetings of my own people.

Following visits to neighboring countries, Their Majesties the King and Queen in June 1960 embarked on a seven-month-long series of State Visits to the United States of America and 13 European countries.

They started the tour in Hawaii on 14 June 1960, greeted at Hickam Air Force Base by William Quinn, then Governor of Hawaii. After four days in Hawaii, Their Majesties the King and Queen flew to the U.S. mainland, arriving in California on 18 June. While in California, they toured Paramount and Desilu Movie Studios, where they sat and chatted at ease with Hollywood executives and legendary stars like Elvis Presley, Bob Hope, and Lucille Ball.

Their Majesties arrived in Washington, D.C., on 28 June, met at the Washington National Airport by President Dwight D. Eisenhower. The Washington Post & Times Herald said in its headline, “President and 75,000 in Streets Greet Thailand King and Queen.”

On 29 June, His Majesty the King addressed a joint session of the United States Congress, ending with these words:

Our two countries have had the best of relations. They started with the coming of your missionaries who shared with our people the benefits of modern medicine and the knowledge of modern science. This soon led to official relations and to a treaty between the two nations. That treaty dates as far back as 1833.

It can be said that from the beginning of our relationship right up to the present time no conflict of any kind has arisen to disturb our cordial friendship and understanding. On the contrary there has been mutual goodwill and close co-operation between our two countries. In view of the present world tension and the feeling of uncertainly apparent everywhere, it is my sincere feeling that the time is ripe for an even closer co-operation. It will demonstrate to the world that we are one in purpose and conviction and it can only lead to one thing – mutual benefits.

On the afternoon of the next day, His Majesty made a private and personal visit to the apartment of Benny Goodman and spent two hours playing music with jazz greats Benny Goodman, Gene Krupa, Teddy Wilson, Urbie Green, Jonah Jones, and Red Norvo.

His Majesty the King also fulfilled his long-time wish to visit his birthplace in Cambridge, Massachusetts. At Mount Auburn Hospital he met Dr. W. Stewart Whittemore, who delivered him on 5 December 1927, along with the four nurses who helped care for him.

From the United States, Their Majesties the King and Queen flew to Geneva, Switzerland, for a few days’ rest and relaxation before embarking on a State Visit to the United Kingdom, which took place on 19-23 July 1960.
