President Volodymyr Zelenskiy has promised to keep Ukraine on top of the international agenda, saying he is banking on having a "productive September" that features new pledges of foreign military aid and fresh diplomatic offensives to punish Russia.
Zelenskiy said he expected to receive from Ukraine's allies more artillery, armoured vehicles, missiles and mine clearance equipment.
"Each partner is aware of our needs. We are expecting decisions," he wrote on Telegram.
On foreign policy, the president said talks were planned on how Ukraine's long-term security can be guaranteed and that his government is also preparing for meetings at the opening of the United Nations General Assembly in New York.
"Global food security is a constant priority," he wrote.
"The Global South will hear Ukraine."
Ukraine was a major exporter of grain to Africa and the Middle East before Russia began blockading its ports as part of the invasion launched in February 2022.
Finally, Zelenskiy thanked the US government for the recent sanctions against various members of the Russian state in connection with the abduction of Ukrainian children.
"We are working on similar sanctions steps by our partners," he wrote.
"The deportation of children - a deliberate and systematic attempt to deprive them of any ties with their families, and an attempt to teach them to hate their country - is a Russian genocidal policy that deserves equal condemnation by everyone in the world."
In March, the International Criminal Court issued arrest warrants for Russian President Vladimir Putin and Russian Children's Rights Commissioner Maria Lvova-Belova for allegedly being responsible for the abduction of children from occupied Ukrainian territories to Russia.
Several regions of Ukraine came under fire from Russian cruise missiles early on Sunday but no damage was reported.
The Ukrainian army said it was slowly continuing to advance after breaking through the Russian defence line near Robotyne, a settlement in the southern Zaporizhzhia region.
The next target for liberation is the nearby village of Novoprokopivka, military spokesman Oleksandr Shtupun said.
Although the Russian air force is stepping up its attacks there, Shtupun interpreted this as a sign that the Russian ground forces no longer have much to counter the Ukrainian advance.
The battlefield claims could not be independently verified.
But foreign military analysts say Robotyne was recently retaken after weeks of fighting and that Ukrainian forces are slowly pushing farther south.
Recapturing cities like Tokmak, and a farther advance on to Melitipol, would mark major wins in Ukraine's counteroffensive.
Both cities in Zaporizhzhia have been occupied by Russian forces since the early days of their invasion.
Ukraine is aiming to advance to the Sea of Azov and cut off the Russian military's supply lines via the so-called land bridge connecting Russia to the Crimean Peninsula.
In Moscow, the defence ministry said a Russian fighter jet was deployed over the Black Sea to intercept a US reconnaissance drone.
Air surveillance systems detected a target moving towards Russian airspace, the ministry said.
As a result, a Su-30 fighter aircraft was dispatched to identify the object.
The Reaper drone turned away in the process and the fighter jet also returned to base, Russian officials said.
There was no immediate comment from the United States.
After earlier incidents over the Black Sea, the US had stressed that its reconnaissance drones were in international airspace.
Russia reported a similar situation with a Reaper drone over the Black Sea in early August.
