The Philadelphia Orchestra may still visit Mongolia on its spring tour of the Far East, though definitely not with its entire contingent.

Due to austerity measures related to a proposed $5.5 billion economic-stabilization package, Mongolia no longer can afford to host the orchestra for its proposed June 2 to 5 visit and outdoor concert in the capital of Ulaanbaatar, orchestra leaders said Friday afternoon.

"We're closely assessing all of our options," said Ryan Fleur, executive vice president of orchestral advancement, emphasizing that no definite plans had been made on how many musicians — if any — would visit Mongolia on this trip. "Changes happen when you work with external partners far away. This time, it has been very public and in a unique aspect of the tour."

In March 2016, when a memorandum of understanding with the government of Mongolia was announced in Washington, the orchestra was discussed in terms of giving a formal indoor concert in a venue that, in true boom-economy fashion, had not yet been built, with a possible second, open-air, performance.

The visit was meant to further cement diplomatic relations between the United States and Mongolia, which have existed for more than 30 years but have heated up during this decade in light of Mongolia's economic advancement and the country's location between Russia and China.

During a September visit to Philadelphia, Mongolian President Tsakhiagiin Elbegdorj said at a City Hall ceremony, "I'm happy to call all of you friends of Mongolia. Let's work together."

As recently as last week, orchestra music director Yannick Nézet-Séguin had expressed continued enthusiasm for Mongolia, saying: "I think this will be one of the great events in the history of the orchestra. Their eagerness to have us there and the wish for Mongolia to get closer to the classical music world is something we can really feel."
