New Delhi, April 15 -- Ukraine and Germany are starting work on plans for the joint production of advanced drones and other battle-tested defense systems, President Volodymyr Zelenskyy said Tuesday, as Kyiv looks to scale up its more than four-year fight against Russia's all-out invasion.

"We have proposed to Germany a bilateral drone deal covering various types of drones, missiles, software and modern defense systems. Our teams are starting concrete work," Zelenskyy said at a joint news conference with Chancellor Friedrich Merz during a visit to Berlin.

Merz said that Germany's commitment to supporting Kyiv's war effort is "a very clear signal" to Russia.

"We will not waver in our efforts to defend Ukraine," he said.
