Trump reportedly ordered his administration to prepare to seek new arms controls agreements with Russia and China, after the White House previously argued the Reagan-era INF was obsolete and failed to account for emerging threats and new technologies. Russia is "open" to discussion of any potential new arms control treaty the US, according to Reuters, citing a Kremlin official. 

Kremlin aide Yuri Ushakov said this weekend on state television: "Firstly, what exists already needs to be honored. We are also ready for new ones, but for that serious negotiations are needed and unfortunately so far nobody has embarked on any," according to Reuters.

It's the first time Russia has signaled it could warm to the idea, after a series of heightening tit-for-tat ratcheting statements over the now effectively collapsed INF resulted in dangerous speculation that either side could deploy short and mid-range missiles to Europe unless the US does it first, precisely the scenario that the 1987 treaty has long prevented.
