The United Kingdom Control of Trade by Sea Order (China and North
Korea) 1953, went into effect in Singapore on March 31, 1953. Since
that time, measures taken to implement the order effectively have
included placing all bunkering of ships, either coal or oil, of over
500 gross registered tons, on a local licensing basis. This places
bunkering under the control of the Controller of Exports and Imports.
Voyage licensing of vessel is under the control of the Master Attendant.
