Perry spokeswoman Lucy Nashed on Monday told The Associated Press that the governor and his wife, Anita, arrived Sunday.
Nashed did not have details on when the GOP governor, who is seeking re-election, and his wife will return. Their itinerary also includes Beijing.
A Perry news release said the couple's travel and accommodations will be paid for by TexasOne, a source of economic development marketing funds for the state.
Perry's office said the delegation to the expo, for "Salute to Texas Week" through June 19, includes Comptroller Susan Combs and Secretary of State Hope Andrade.
Perry in November faces Democrat Bill White in the race for governor.
