Chinese service robot maker Pudu Robotics is preparing for a Hong Kong listing, Nikkei Asia reported Wednesday, citing founder and chief executive Felix Zhang.

Speaking on the sidelines of the Beyond Expo technology exhibition in Macau, Zhang said the listing would support the company's international expansion, though he did not provide a timetable, according to the report.

Zhang reportedly added that the overseas markets account for the majority of Pudu's business, with Europe and the U.S. contributing about 60% of revenue, compared with less than 20% from China.
