The Kremlin has reacted harshly to the promise that Republican Party presidential candidate Mitt Romney made to toughen up on Russia, should he get elected President of the USA.

“It is inadmissible for US-Russian relations to fall hostage to US election debates,” Dmitry Peskov, spokesman for Russian President Vladimir Putin, said on Friday, as cited by RIA Novosti.

Peskov was commenting on Mitt Romney’s presidential nomination acceptance speech.
