Your attention is invited to the second sentence in the post. Thank you.

Most early Americans were against the slave trade. The Carolinas and Georgia required that, as a condition of joining the Union, no prohibition of the slave trade could be made for at least 20 years. 20 years later the slave trade was banned in America (1808). The USS Constitution prowled the west coast of Africa freeing slaves. Americans created Liberia for freed slaves.

Jefferson was also against slavery, but he believed Blacks were inferior and couldn't see any path to their emancipation. The only part of the Declaration of Independence that was substantially edited -- actually removed -- was a bitter polemic against the slave trade and King George's participation in it.

Jefferson signed the law ending the slave trade. It was known in England that America intended to end the Atlantic trade, and it was a source of both irritation to British abolitionists that the Americans might end it first, and a source of arguing against ending it on the British side by anti-American forces in Parliament. I don't think there is any evidence that either man knew or wrote to the other; in any case, their formative opinions on slavery could not have had any reciprocal influence.

a quick google search produced only this:

"Where Martin Luther King Jr. had spoken in his timeless “I have a dream” speech of “a beautiful symphony of brotherhood” – Wilberforce had, 155 years before, written of a “concert of benevolence” in an abolition letter to President Thomas Jefferson.

"In words that Dr. King would have understood well Wilberforce had also written: “In the Scriptures no national crime is condemned so frequently, and few so strongly, as oppression and cruelty, and the not using our best endeavours to deliver our fellow-creatures from them.”... "

No clear indication of how many letters were exchanged, or of how much influence, if any really, Wilberforce had on Jefferson.
