It has been a decade since former Mayor Michael R. Bloomberg decided to ramp up New York City’s efforts to attract more tourists, and city officials say there is no end to the influx on the horizon.

In Berlin on Wednesday, Fred Dixon, the chief executive of New York’s tourism-marketing agency, NYC & Company, plans to announce a forecast of 59.7 million visitors this year. That would exceed last year’s record of 58.3 million visitors by 2.4 percent and keep the city on pace for a goal of drawing 67 million annual visitors by 2021, Mr. Dixon said in an interview.

The tourists have kept flowing into New York from around the country and the rest of the world despite turmoil in many places, a slowing economy in China and a strengthening American dollar that weakens the buying power of foreigners, Mr. Dixon said. Despite the slowdown in China, the country is expected to be a growing source of visitors to the city in 2016, which has been declared “U.S.-China tourism year,” he said.

NYC & Company is projecting about 920,000 visitors from China this year, an increase of 8.2 percent from the preliminary estimate of about 850,000 in 2015. China is the fourth-largest source of foreign visitors to the city, behind England, Canada and Brazil.
