HIROSHIMA, Japan, May 19 (Reuters) - Leaders of the world's richest democracies acted on Friday to stiffen sanctions against Russia, while a draft communique to be issued after their talks in the Japanese city of Hiroshima stressed the need to reduce reliance on trade with China.

The Group of Seven (G7) leaders, to be joined this weekend by Ukrainian President Volodymyr Zelenskiy, pledged to restrict any exports to Russia that could help President Vladimir Putin's invasion of his neighbour and to stop sanctions-busting.

"Today’s actions will further tighten the vice on Putin’s ability to wage his barbaric invasion and will advance our global efforts to cut off Russian attempts to evade sanctions," U.S. Treasury Department Secretary Janet Yellen said in a statement accompanying a raft of new U.S. measures.

A statement issued by G7 leaders said restrictions would cover exports of industrial machinery, tools and technology useful to Russia's war effort, while efforts would be pursued to limit Russian revenues from trade in metals and diamonds.

On China, which G7 powers increasingly see as a threat to economic security, they were to agree that its status as the world's second largest economy necessitated efforts to foster cooperation, an early draft of the final communique seen by Reuters said.

"Our policy approaches are not designed to harm China, we do not seek to thwart China's economic progress and development," noted the draft, which is still subject to change, calling for "stable and constructive" ties with Beijing.

The draft nonetheless urged measures to "reduce excessive dependencies" in critical supply chains and counter "malign practices" in technology transfer and data disclosure.

It reaffirmed the need for peace in the Taiwan Strait and urged China to press Russia to end aggression in Ukraine.

NUCLEAR SYMBOLISM

The G7 - the United States, Japan, Germany, Britain, France, Italy and Canada - will use the three-day meeting to debate strategy on a Ukraine conflict that shows no sign of easing.

The summit venue, Hiroshima, was destroyed by U.S. nuclear bombings 78 years ago that ended World War Two. Japanese Prime Minister Fumio Kishida, who represents Hiroshima in Japan's lower house of parliament, said he chose it for the global gathering to focus attention on arms control.
