July 23 (Reuters) - Australian shares fell sharply on Monday as financial markets fretted over global trade war tensions after U.S. President Donald Trump threatened more tariffs on Chinese imports.
Financials were the biggest drag on the S&P/ASX 200 index , which fell 0.9 percent, or 55.9 points to 6,230.0 by 0200 GMT. The benchmark rose 0.4 percent on Friday.
Trump said on Friday he was ready to impose tariffs on all $500 billion of imported goods from China, as a trade dispute between the world’s two biggest economies intensified with no signs a resolution was near at hand.
Trump’s more aggressive protectionists policies have sparked retaliatory measures from countries around the world, rattling financial markets worried about the impact on global growth.
Christopher Conway, head of research and trading at Australian Stock Report said: “It’s a couple of factors coming together, but for the most part it is the trade war tensions that’s driving our markets lower.”
Financial stocks tugged on the benchmark, with the main financial index down one percent.
Westpac Banking and Commonwealth Bank of Australia led the losses among the ‘Big Four’ banks, down 1.2 percent and 1.1 percent, respectively.

The Aussie mining index was down 0.9 percent, as commodity prices remained pressured by global trade tensions.
Mining-to-home improvement conglomerate Wesfarmers was among the top losers on the benchmark. The firm expects the demerger of its Coles supermarket chain to be completed by November and plans to retain 15 percent of the spin-off.
Wesfarmers was down as much as 1.3 percent.
