The government set up a new office Tuesday to oversee efforts to promote bullet-train sales in other countries planning to introduce high-speed railway systems.

The 14-member international railway strategy office at the Land, Infrastructure, Transport and Tourism Ministry will work with East Japan Railway Co. and other railway firms to promote exports of shinkansen trains, officials said.

The United States is planning to introduce high-speed railways under its Green New Deal initiative, which focuses on investment to help the environment and stimulate the economy. Countries such as Brazil and Vietnam are also looking at high-speed rail.

Japan's bullet-train system costs less in maintenance than its rivals, such as the French TGV and German ICE systems, and features excellent safety features including an early earthquake detector to prevent derailments, the officials said.
