Politics this week

Joe Biden and Vladimir Putin met in Geneva for a summit. It lasted less than four hours, but both men described it as constructive. The two sides agreed to return their ambassadors, who were recalled earlier this year, and said they would work on new nuclear-arms-control measures. Mr Biden criticised Russia’s human-rights record, but said the topic should be dealt with separately from other matters, such as security and climate change. Mr Putin denied that Russia engages in cyber-attacks.
