Franklin Roosevelt actually said...

"This Executive Order... is designed among other things to prevent the use of the financial facilities of the United States and trade between Japan and the United States."

"This measure, in effect, brings all financial and import and export trade transactions in which Japanese interests are involved under the control of the Government."

"The inclusion of China in the Executive Order, in accordance with the wishes of the Chinese Government, is a continuation of this Government's policy of assisting China."

"I, Franklin D. Roosevelt, President of the United States of America, do hereby amend Executive Order No. 8389 of April 10, 1940, as amended."
