Asian shipowners have urged the Suez Canal Authority (SCA) and Panama Canal Authority (ACP) to avoid “sudden and significant” changes to tolls without prior consultation.

The statement comes after the SCA raised toll charges twice in a matter of months, and as the Panama Canal proposes longer-term changes to its toll system.

The Asian Shipowners’ Association (ASA), following its interim policy committee meeting, said in a statement it was “confused” by the SCA’s decision, with only 48 hours notice, to raise charges on 1 March by between 7% and 20%.
