Ukraine's President has called on the West not to create panic amid the build-up of Russian troops on his country's borders.

Iran PressEurope: Volodymyr Zelensky told reporters that warnings of an imminent invasion were putting Ukraine's economy at risk.

On Thursday, US President Joe Biden claimed that he believed Russia could attack its neighbor next month.

Russia, however, denies it is planning to invade and on Friday its foreign minister said Moscow did not want war.

While Russia has about 100,000 troops on Ukraine's borders, Zelensky said he did not see a greater threat now than during a similar massing of troops last spring.

"There are signals even from respected leaders of states, they just say that tomorrow there will be war. This is panic - how much does it cost for our state?" he told the press conference in Kyiv.

Zelensky also criticized the UK, US, and Australian withdrawal of diplomats' families from Ukraine, saying it had been a mistake.

"The destabilization of the situation inside the country" is the biggest threat to Ukraine, he said.

The US has rejected a key Moscow demand that Nato rules out Ukraine joining the defense alliance - but insisted it was offering Russia a " serious diplomatic path".

Russian President Vladimir Putin later accused the West of ignoring Russia's security concerns.

But he said he would study the US response before deciding what to do, according to a Kremlin readout of a call between Putin and his French counterpart.

France said the two leaders had agreed on the need to de-escalate and its President Emmanuel Macron told Putin that Russia must respect the sovereignty of its neighboring states.
