• Competition
Despite having enjoyed a privileged position for many years, the canal is increasingly facing competition from other quarters. Because canal tolls are expected to rise, some critics have suggested that the Suez Canal may become a viable alternative for cargo en route from Asia to the U.S. East Coast. The Panama Canal, however, continues to serve more than 144 of the world's trade routes and the majority of canal traffic comes from the "all-water route" from Asia to the U.S. East and Gulf Coasts via the Panama Canal.
In 2013, Nicaragua has reportedly awarded a Chinese firm a 50-year concession to the Hong Kong-based HKND Group to build a channel through the waters of Lake Nicaragua. The envisioned channel would be 22 metres deep and 286 km (178 miles) long, allowing the passage to ships of up to 250,000 tonnes.
