Notably, US President Joe Biden sought advice from New Zealand Prime Minister Jacinda Ardern over tackling violence in the United States as shooting incidents in America have been increasing in recent days.

Biden referred to the 2019 Christchurch slaying of 51 people in mass shootings targeting Muslims. The incident prompted New Zealand to ban military-style rifles. A gun buy-back was also instituted.

"We need your guidance," Biden said during the meeting with Arden in the Oval Office. "Your leadership has taken on a critical role in this global stage - and it really has - galvanizing action on climate change, the global effort to curb violence, extremism, and online, like happened in Christchurch," he added.
