A separate entry lane will be set up at Tokyo's Narita International Airport for guests attending the upcoming meeting of the International Monetary Fund and the World Bank, airport officials said Saturday.

About 20,000 people from 188 countries are expected to attend the event, which is scheduled to open Tuesday. VIPs are estimated at 4,000 to 5,000 people, of whom about 90 percent are expected to arrive at Narita airport, according to Japan's Finance Ministry.

The measure is intended to offer guests smooth entries at the nation's biggest international gateway, as the majority of the participants are expected to arrive on commercial flights along with other travelers and visitors, according to airport officials.

On arrival, IMF-World Bank visitors will be transferred from the regular passenger terminals to another airport facility for customs and immigration procedures. It will be the first attempt to offer such service at Narita airport, said airport officials.
