Putin meanwhile said Russian Federation would work with China on the North Korean nuclear issue, ahead of the highly anticipated meeting between US President Donald Trump and North Korean leader Kim Jong-un in Singapore.
Expelled from the club of rich nations in 2014 after it seized Crimea from Ukraine, Russia has tried to rebrand itself as an Asian power rather than a European one, abandoning visions once eagerly embraced by Putin of a common economic space stretching from Lisbon to Vladivostok.
Xi also presented Putin with China's first "friendship medal", calling him a "good and old friend of the Chinese people" during a live broadcast on state television.

On Saturday, Trump repeated his desire to have a sunset clause in an updated NAFTA deal, a demand Trudeau rejected again.
Before the medal ceremony, Putin said the two heads of state had enjoyed "fruitful" talks.
The White House has downplayed reports of tensions between the leaders, but stressed that the president is committed to overhauling trade practices. Moreover, later news came that Trump had not only mentioned the possibility of a meeting but also invited Putin to Washington.
The Trump administration announced two weeks ago that it would investigate whether auto imports hurt US national security, the first step toward tariffs similar to the ones he imposed on steel and aluminum imports last week.
On Saturday, G7 participants slammed Russia's support for the Syrian regime and Moscow's attempts to undermine democracy at a meeting in Quebec City, Canada.
Mr Trump was already at odds with the rest of the group - the UK, Canada, France, Germany, Italy and Japan - over the imposition of tariffs on steel and aluminium.
"Looking forward to straightening out unfair Trade Deals with the G-7 countries".
"What is important is that the UK and the United States actually come together in a whole variety of ways to talk about the issues that matter to us both".

"The principle of a dialogue was agreed this afternoon", the French official told reporters. "Not fair to our farmers!"
"The president has inexplicably shown our adversaries the deference and esteem that should be reserved for our closest allies", McCain said.
Kudlow says Trump won't let a Canadian prime minister push him around on the eve of his summit with North Korean leader Kim Jong Un.
As he prepared to travel to Canada, he ramped up his blast of Canada on Twitter this morning over what he says are unfair trade practices as the USA president prepares to make his Canadian debut later today.
"But I believe it's a technical issue", he said.
"We can differently assess decisions that are taken by the United States, including by the USA president".
