Construction workers on Tuesday laid the last piece of a railway that will link southwest China's Yunnan province with the Association of Southeast Asian Nations countries.

The Yuxi-Mengzi Railway has a total length of 141 km with a designed maximum speed of 120 km per hour. It passes through 35 tunnels and crosses 61 bridges, which together account for 54.95 percent of the line's total length.

The railway is part of the eastern line of the planned Pan-Asia Railway network, an international railway project that will also consist of central and western lines.
