It will take more than the abrupt cancellation of a high-speed train deal with Mexico to derail China Railway Construction Corp.'s ambition to become a global force in transport projects and take on the likes of Siemens, Alstom and Bombardier.

State-owned CRCC and its partners will bid again for the $3.75 billion project, despite saying it was "exceptionally shocked" by Mexico's reversal following objections from opposition lawmakers angry that the bid had been uncontested.

About two weeks after the cancellation, CRCC announced it had signed a $12 billion contract to build a railway along the coast of Nigeria, part of a concerted effort to secure business abroad and push China's "railroad diplomacy." It was the largest single overseas construction deal won by a Chinese firm.
