Vladimir Putin has condemned Western sanctions imposed by Russia over its war in Ukraine, calling it a fever that threatens the entire world.
Addressing an economic forum in Vladivostok, he said Russia was countering economic "aggression" from the West.
But the Russian president warned that living standards for Europeans were being hit by sanctions while poorer countries were losing access to food.
He also said that Europe is cheating poor countries with Ukrainian grain.
For months Ukraine's seaports were blocked by Russian forces, but after exports resumed in early August, Russia's leader insisted that only two grain ships had gone to Africa - which is not the case. He said he wanted to talk about revising the deal, which Ukraine rejected as groundless.
Russia launched its offensive on February 24 and now occupies about a fifth of Ukraine. Six months later, he has been pushed back from Kyiv and the surrounding areas in the north and now faces a Ukrainian counter-offensive in the south and east.
Western countries have imposed sanctions on a number of Russian individuals, businesses and government institutions in response to the war. The European Union has sought to reduce dependence on Russian gas and oil, and Moscow has shut down its key Nord Stream 1 gas pipeline to Germany, blaming technical problems.
Energy prices have soared and EU ministers are meeting on Friday to address the crisis. The Russian leader dismissed a proposal to cap Russian gas prices as foolish.
Mr Putin told his audience that the West was trying to impose its behavior on other countries. He said many companies had rushed to leave Russia, but "now we see how production and jobs in Europe are closing one after the other". However, Russia is also feeling the pinch, with inflation rising and companies struggling to import much-needed parts.
The European Union already bans direct flights from Russia, and last week its 27 member states agreed to make the process of obtaining visas for Russians more onerous, further angering Moscow. A very expensive Schengen visa covering 22 EU countries is also likely to become more expensive. The three Baltic states have now gone further with an agreement barring Russians from transiting through Russia and Belarus, unless they are lorry drivers or for family and humanitarian reasons.
Russian citizens will have to pay an additional 45 euros for EU visas .
In a speech aimed at Western observers as much as a domestic audience, President Putin said people's confidence in the dollar, euro and pound was eroding. Russia, meanwhile, was emerging from the war with its sovereignty strengthened: "I'm sure we've lost nothing and we won't lose anything."
Ukraine's Foreign Minister Dmytro Koliba said Russia was trying to blackmail Europe with its energy resources: "Putin wants to destroy the stability and well-being of every home in Europe."
Top Chinese lawmaker Li Zhanshu attended the forum and the Russian president said that "no matter how much one wants to isolate Russia, it is impossible to do so". Russian news agencies say that President Putin will meet with his Chinese counterpart Xi Jinping in Uzbekistan next week.
Until a UN-sponsored deal was agreed to lift Russia's blockade of three Ukrainian Black Sea ports, grain exports were reduced to a minimum. Shipments have gradually resumed and a UN-chartered vessel arrived in Djibouti last week with 23,000 tonnes. The grain has now arrived in Ethiopia in 60 lorries, with the aim of feeding more than half a million people in the drought- and civil-war-ravaged country.
Other ships have left for Yemen and Sudan, while several ships have gone to Egyptian ports.
Under the agreement, all cargoes are cleared from a common center in Turkey. The center says 2 million tonnes have been authorized so far, including ports in Turkey and the Middle East as well as the European Union.
But President Putin accused many European countries of acting like colonialists and said he would propose to Turkish President Recep Tayyip Erdogan to limit destinations for Ukrainian exports.
"Not counting Turkey as an intermediary country, practically all the grain exported from Ukraine is destined not for the poorest and developing countries, but for the countries of the European Union," the Russian leader argued.
A Ukrainian presidential adviser accused him of making baseless statements, telling Reuters news agency that the Russian leader was trying to sway public opinion around the world and put pressure on the United Nations.
