Mr Zelensky made this statement after a meeting with Defense Minister Rustem Umerov, Commander of the Armed Forces Aleksandr Syrsky and Chief of the General Staff Andrey Gnatov on July 13.
"Our units will do everything possible to bring the war into Russian territory. We are preparing for new long-range attacks," President Zelensky wrote on X.
He added that Ukraine is preparing for the visit of US presidential special advisor Keith Kellogg and will "work with partners on the supply of weapons and expanding joint production of essential defense assets".
In recent attacks deep into Russian territory, Ukraine has targeted military airports with strategic bombers in parts of Russia last month.
Ukrainian drones and missiles also continuously attack apartment buildings and other civil infrastructure. According to Moscow, Ukraine must take responsibility for the derailment of a passenger train on March 31, which killed seven people.
While the US continues to act as a major sponsor, the European Union (EU) is also stepping up efforts to strengthen its internal defense capabilities. Hundreds of billions of euros have been pledged by EU member states in recent months to expand the production capacity of weapons, ammunition and military equipment to provide long-term support to Ukraine.
Boosting domestic production not only helps reduce dependence on the US, but also reflects a long-term trend: the EU is preparing for a prolonged conflict, with Ukraine playing a strategic "frontline" role.
According to Major General Christian Freuding, Germany's military aid coordinator for Ukraine, Berlin will provide the first batch of long-range missiles funded by the German budget in the coming weeks.
US President Donald Trump also said last week that the Pentagon will resume military equipment transfers to Ukraine after a period of interruption. The new aid package could be the first under Trump's new term, highlighting the central role of the United States in supporting Ukraine, according to sources.
On the Russian side, Moscow officials have repeatedly stated that Ukraine's use of Western-supplied weapons to attack Russian territory would be considered a "direct combat" by NATO countries.
The Russian Foreign Ministry stressed that many modern weapons systems such as cruise missiles or attack drones cannot be operated by Ukrainian soldiers without direct technical support and training from Western experts.
