JAKARTA, Sept. 13 (Xinhua) -- The number of foreign holiday makers travelling into Indonesia inched up 12.92 percent to 9.06 million people from January to July year-over-year, the national statistics bureau announced on Monday.

On months, the arrival shot higher 16.57 percent to 1.54 million people in July, head of the bureau Kecuk Suhariyanto disclosed.

The official said that the hike continued the uptrend which has kicked off since June and for July alone, it was amplified by the commencement of holiday season in American continent, he cited.

"Countries situated in the American continent have entered summer holiday season," Suhariyanto said at the bureau headquarters.

The enlargement of the schedules of direct flights overseas also factored in addition to the summer holiday factor, he cited.

China, followed by Malaysia, Timor-Leste, Singapore and Australia, is the most contributing country to the Indonesian foreign tourist arrivals in May, the official noted.

Indonesia has estimated a total of 17 million foreign holiday makers arriving in the country this year after logging a 15 million figure in 2017.
