Russian President Vladimir Putin on Thursday said his country would develop missiles banned under the now-defunct Intermediate-Range Nuclear Forces (INF) Treaty in response to the announced deployment of new US hardware in Asia.

"We will make such missiles, of course, but we will not deploy them in the regions where no ground-based missile systems of this class of US manufacture have emerged," Putin said in comments carried by the state-run TASS news agency.

Last month, the US and Russia formally withdrew from the key Cold War-era treaty, which governed the use and deployment of such missiles. In response to the treaty's collapse, the US said it would deploy previously outlawed missiles in Asia "sooner rather than later."

"We regret this and feel certain alarm," said Putin. "If US missiles are deployed in Japan or South Korea, we understand that this will be done to counterbalance potential threats from North Korea, but it will create certain considerable problems for us."

'Unknown future'

Tomas Olivier, who heads international relations at the Netherlands-based DAEL Security, told DW that Russian concerns about the US deployment in Asia are grounded in a strategic outlook that takes into account a changing global security environment.

"From a Russian perspective, with the rise of new Asian military powers and innovative technology, and additionally the possible future deployment of a significant amount of land-based US missiles in Asia, their concern is coherent," said the former Dutch Defense Ministry senior officer.

When asked about how it would affect global security, Olivier said the latest development is a "worrying step into an unknown future with hypersonic nuclear missiles, unexplored military alliances and shifting political rhetoric."

Global concerns

The US decision to deploy ground-based intermediate-range conventional missiles not only triggered criticism from Russia but also China.

The Chinese Foreign Ministry last month said Beijing "will be forced to take countermeasures should the US deploy intermediate-range ground-based missiles in this part of the world."

European officials have warned that the continent's security is in jeopardy following the collapse of the INF Treaty, with German Foreign Minister Heiko Maas calling for renewed efforts in disarmament and arms control "in order to prevent a new nuclear arms race."
