A ship is guided by a tugboat through the Miraflores Locks at the Panama Canal near Panama City on July 31, 2014. Next August 15 marks the 100th anniversary of the Panama Canal, one of the greatest engineering works of the 20th century and through which five percent of the maritime world trade goes. Panama took control of the 80-km-long canal and the 1,426-square-km enclave that surrounds it at midnight on December 31, 1999 according to the 1977 handover treaty signed by then-presidents of the US, Jimmy Carter and Panama, Omar Torrijos.
