Ukraine will be the main topic at the NATO summit in Washington.
According to the White House, US President Joe Biden will meet with Ukrainian President Volodymyr Zelenskyy at the NATO summit to discuss and announce new steps to strengthen Ukraine's air defence and military capabilities.
"The Washington summit will send a strong message to Putin that if he thinks he can outlast the coalition of countries supporting Ukraine, he is sorely mistaken", said a White House official.
The plan is to announce long-term efforts for Ukraine in the form of logistical support, defence institution building and cooperation with NATO.
