Presidents Donald Trump and Vladimir Putin have expressed support for better ties between the US and Russia. In some ways, the countries have different interests. Trump would like to see lower energy prices to boost the US economy, while Putin needs higher prices to support his war effort. However, both Trump and Putin have a mutual interest in growing the oil and gas sector and likely will join forces to undermine progress at future international climate talks. The negative consequences for health and food security among the most vulnerable countries will likely be severe.
