Later, Hanna also took to Instagram to describe her "interactive and pleasant conversation" with the royal.
"Today I welcomed Prince William and the Duchess of Cambridge Kate to Jamaica on behalf of the Leader of the Opposition in celebration of the Queen's platinum Jubilee," she wrote.
"We had a very interactive and pleasant conversation throughout the proceedings as we talked about family, our cultures and our people.
"There's no doubt at this time that we all seek our true independence and want to develop systems and strategies where we become free from the monarchy. But until then we will always remain a courteous and respectful country."
She continued: "I am a firm believer in reparations and as such when I was Minister of Youth and Culture I led the reparations committee which made strides in developing submissions to Britain which examined the economic cost of slavery to our country.
"I welcome them wholeheartedly with our warm hospitality, and look forward to us having productive discussions about our future."
Kate's exchange with Hanna comes amid a few rocky patches on the royal tour. Protests and criticisms were aimed at Prince William and his wife ahead of their visit to Jamaica, with a coalition of Jamaican human rights and equality activists calling on the Queen and the UK government to apologise for the ramifications of colonialism and chattel slavery the British Empire inflicted on Caribbean countries.
An open letter was signed by prominent politicians, business leaders, doctors and musicians, with a protest taking place outside the British High Commission.
"We note with great concern your visit to our country, Jamaica, during a period when we are still in the throes of a global pandemic and bracing for the full impact of another global crisis associated with the Russian/Ukraine war," the letter reads.
"We see no reason to celebrate 70 years of the ascension of your grandmother to the British throne because her leadership, and that of her predecessors, has perpetuated the greatest human rights tragedy in the history of humankind."
The letter also highlighted the "crimes against humanity" committed by the British Empire, which included the "exploitation of the Indigenous people of Jamaica, the transatlantic trafficking of Africans, the enslavement of Africans, indentureship and colonisation".
The royal couple embarked on their tour of the Caribbean, which includes Belize, Jamaica and The Bahamas, on March 19. The trip coincided with the Queen's highly anticipated platinum jubilee which marks 70 years of her rule.
