Russia plans to spend a total of 34 trillion rubles ($600 billion) on national defense, security and law enforcement between 2022 and 2025, according to a source familiar with Russian Finance Ministry accounts on Friday, under the country's latest spending plan.

Russia is waging a costly military campaign in neighboring Ukraine, and this week it announced the mobilization of another 300,000 soldiers.

According to the latest figures, Russia will spend a total of 18.5 trillion rubles between 2022 and 2025 on national defense, including 4.7 trillion rubles this year.

Previously, Russia had planned to spend 3.5 trillion rubles on national defense this year out of a total of 10.9 trillion rubles for 2022-2024.

This year's spending on security and law enforcement remains as planned, at 2.8 trillion rubles.

Previous spending on security and law enforcement was 8.7 trillion rubles for the period 2022-2024 compared to the 15.6 trillion rubles planned for 2022-2025.

The source did not provide other data on the allocations or other details, and on the other hand, the Russian Finance Ministry refused to comment, according to Reuters.
