The assessment by the Office of the Director of National Intelligence said that China has "become an even more critical economic partner for Russia since the invasion of Ukraine" and that it is "pursuing a variety of economic support mechanisms for Russia that mitigate both the impact of Western sanctions and export controls."

African leaders gathered in St. Petersburg for a Russia-Africa summit urged President Vladimir Putin to move ahead with their peace plan for the conflict in Ukraine and provide guarantees for the safe passage of grain to their countries.
"The African (peace) initiative deserves the closest attention, it mustn't be underestimated," Congo Republic President Denis Sassou Nguesso told Putin and African heads of state, according to a Reuters translation.
"We once again urgently call for the restoration of peace in Europe," he added.
Egypt's President Abdel Fattah al-Sisi also called on Russia to restore the Black Sea Grain Initiative, which Moscow exited last week. Prior to the withdrawal, it had allowed for the safe, global export of grain from Ukraine.
