JAKARTA — In his previous life as a small-time furniture exporter and exhibitor, Joko Widodo was used to erecting stages. But in early November, just days after being sworn in as the president of Indonesia, he will now be sharing a stage with the world’s most powerful leaders.

Between Nov. 10 and Nov. 16, Mr. Joko will, in succession, attend the Asia-Pacific Economic Cooperation (APEC) summit meeting in Beijing; the Association of Southeast Asian Nations (Asean) leaders’ meeting and the East Asia Summit, both being held in Naypyidaw, Myanmar; and a meeting of G-20 leaders in Brisbane, Australia.

Mr. Joko, who was sworn in as president on Monday, comes into office with no foreign policy experience, and his introduction into international affairs will be, according to analysts, a trial by fire. “The most important thing is meeting these leaders face to face,” Mr. Joko said in an interview shortly before his inauguration, “and develop those relationships.”

That may be easier said than done, given that he doesn’t have much in common with his counterparts. Born in a slum in the province of Central Java, Mr. Joko, 53, a former carpenter, is the first Indonesian president not to come from the country’s political elite or be an army general.
