And 24 hours after Putin's victory, there has been no public comment from the White House.
In London the only response from Downing Street was that it is waiting for an independent report by observers of the electoral process.
Here's a roundup of global reaction:
Just a day after Xi Jinping was unanimously re-appointed President, the Chinese leader said Beijing was willing to work with Moscow.
"Currently, the China-Russia comprehensive strategic cooperative partnership is at the best level in history, which sets an example for building a new type of international relations," Xi said in a message to Putin.
However, the European Union said "violations and shortcomings" in the election flouted international standards, pointing to one-sided media coverage and curbs on political freedoms.
"We expect Russia to address the violations and shortcomings," an EU statement said.
British Prime Minister Theresa May's spokesman said the Organisation for Security and Coopeation in Europe "has deployed an election observation mission to Russia and we will await their assessment before making any comment."
German Chancellor Angela Merkel was to congratulate Putin, but the message will also raise "challenges" in their relations, her spokesman said.
Berlin and Moscow have "differences in opinion" on issues ranging from Russian politics to the conflicts in Ukraine and Syria.
"Nevertheless, the continuous contact with Russia's leadership is very important to us."
Foreign Minister Heiko Maas was more critical, saying: "We certainly cannot talk in all respects about a fair political contest as we know it."
It was "unacceptable" that the election also took place in Crimea, which Russia annexed from Ukraine four years ago in breach of international law, Maas said.
"In this respect, we assume that Russia will remain a difficult partner."
Poland also took up the Crimea theme with the foreign ministry saying the vote on the peninsula was "illegal" and urged respect for Ukrainian territorial integrity.
In a phone call with Putin, French President Emmanuel Macron wished him "success for the political, democratic, economic and social modernisation" of Russia.
But he also urged Putin to shed light on the 'unacceptable' double agent poisoning in Britain and expressed concern over the war in Syria.
Hungary's Prime Minister Viktor Orban led the applause from some friendly former Soviet-bloc states with a letter of congratulations.
Bulgarian President Rumen Radev said he looked forward to working with Putin.
Turkey's President Recep Tayyip Erdogan, who has cultivated closer cooperation with Putin, especially on Syria, congratulated the Russian leader by telephone, state media said.
They also discussed a three-way summit on Syria due to be held with Iranian President Hassan Rouhani in Istanbul on April 4.
'Denuclearise North Korea'
Japanese Prime Minister Shinzo Abe congratulated Putin and the two leaders agreed to work together for North Korea's denuclearisation, the Japanese foreign ministry said.
"The two leaders confirmed their close cooperation in realising North Korea's denuclearisation" before an expected summit between US President Donald Trump and North Korean leader Kim Jong Un, it said.
"The Russian people's exceptional trust in you is a natural outcome of your outstanding national performance," Syrian President Bashar al-Assad told his close ally in a congratulatory cable.
'Develop relations further'
Iranian President Rouhani congratulated Putin on his "decisive victory" and pledged to boost ties.
"I am sure that during your new term, relations between our two countries will develop further," he said.
Iran and Russia have strengthened ties, both giving major military and financial backing to Syrian President Bashar al-Assad.
Israeli Prime Minister Benjamin Netanyahu said in a statement he hoped to deepen "our personal dialogue" and "to continue working together intensely in confidance and harmony."
Egyptian President Abdel Fattah al-Sisi sent his "warmest congratulations".
"(Sisi) lauds the strategic relations that the two countries share and their keenness to further enhance them so as to realise the interests of both peoples," a statement said.
The presidents of leftist regimes in Venezuela and Bolivia congratulated Putin for an "overwhelming" victory.
Russia and Venezuela are "brother countries" as both must "face the frequent manoeuvres of imperialism" to "impose doctrines of world supremacy," said President Nicolas Maduro.
Bolivian President Evo Morales said on Twitter that Putin's win "guarantees geopolitical equilibrium and world peace before the onslaught of imperialism".
'Health and happiness'
Saudi Arabia's new strongman, Saudi Crown Prince Mohammed bin Salman and his father King Salman wished Putin "constant good health and happiness and his people steady progress and prosperity".
