Congress finally acted in the spring of 1784. On May 7, Congress authorized its Ministers in Paris, Franklin, Jay, and Adams, to conclude treaties of amity and commerce with Russia, Austria, Prussia, Denmark, Saxony, Hamburg, great Britain, Spain, Portugal, Genoa, Tuscany, Rome, Naples, Venice, Sardinia, and the Ottoman Porte as well as the Barbary States of Morocco, Algiers, Tunis, and Tripoli.
My guess is almost certainly no, given that Venice and Genoa were city states and that US didn't appoint ambassadors to each European nation until the 19th century.
