Argentina hasn’t registered to attend the COP30 climate summit, according to people familiar with the matter, suggesting the country may join the US in sitting out the annual United Nations-sponsored talks that start in Brazil later this week.

The White House said last week that no high-level US officials will be going to the conference in the city of Belém. Almost 190 countries have confirmed their intent to send representatives, COP President André Corrêa do Lago said on Monday.
