United States Ambassador to the U.N. Linda Thomas-Greenfield is among those who participated in a Wednesday event on the sidelines of the U.N. General Assembly that highlighted efforts to decriminalize consensual same-sex sexual relations.

Thomas-Greenfield in her remarks during the largely virtual U.N. LGBTI Core Group event noted consensual same-sex sexual relations remain criminalized in more than 70 countries.

“For millions of people it is illegal for them to be who they are, to love who they love. We need to repeal and eliminate these laws,” she said. “For our part, the United States is using our diplomacy, our foreign assistance and every tool we have to protect human rights, empower civil society and support local LGBTQI movements.”

The U.S. is one of 35 countries that are members of the Core Group.

Wednesday’s event also highlighted efforts to decriminalize transgender people and repeal laws that specifically target them.

“We need more countries to join this committed group,” said Thomas-Greenfield. “Together, let’s do everything we can to protect human rights and promote equality for all.”

Acting OutRight Action International Executive Director Maria Sjödin and activists from Bhutan, Botswana, Guyana, Mozambique, Angola, Panamá and India took part. Victor Madrigal-Borloz, the independent U.N. expert on LGBTQ issues, and Nikkie de Jager, a Dutch U.N. goodwill ambassador known as NikkieTutorials who is trans, also participated.

“Decriminalization is a very basic demand,” said Sjödin. “Given how many countries have these laws on the books, it is still a priority.”

Herbert, who is British Prime Minister Boris Johnson’s LGBTQ envoy, noted consensual same-sex sexual relations remain criminalized in 35 of the Commonwealth’s 54 countries. Herbert also announced the U.K. will give an additional $2.75 million to “support LGBT+ individuals in Commonwealth countries, including to those seeking to address outdated legislation that discriminates against women, girls and LGBT+ individuals.”

“We are clear that tackling discrimination is only one part of the issue,” said Herbert. “We must encourage countries as well to put in place laws that protect their LGBTI citizens going forward.”

President Biden in February signed a memorandum that committed the U.S. to promote LGBTQ rights abroad. The decriminalization of consensual same-sex sexual relation is one of the White House’s five global LGBTQ rights priorities.
