I'll presume you are just ignorant, and not just spewing Russian propaganda.
Ukraine has always had a very significant manufacturing and technology base. As one example the Moskva was built in Ukraine many years ago. And it was sunk by a missile system developed and built in Ukraine.
Ukraine used to sell armaments around the world. Its Stugna-P anti-tank missile was a popular export. Today you can see videos of Ukrainian soldiers using Stugna-P units built for export to destroy Russian tanks. Their customers in the middle east must be complaining about the slow deliveries now.
In the future many nations will want to buy the Ukrainian hardware that has proven effective.

And... Russian arms sales had been about 20% of their revenue and energy ~40%.
And... the Chinese have been upping their arms sales lately while cutting Russian purchasing.
