Canadian Prime Minister Justin Trudeau has said he hopes to reach a deal with the US to scrap customs duties for steel and aluminium products later this month.

"We will meet at the G20 in Argentina and we hope to have good news at that point," Trudeau said in reference to US President Donald Trump.

The Group of 20 (G20) leading global economies is to hold a two-day summit in Buenos Aires from 30 November.

Trudeau said he had spoken briefly with Mr Trump in Paris, where they had both taken part in commemorations to mark the end of World War I.

He said they had both agreed to work on eliminating these tariffs.

On 1 June this year, the US slapped tariffs on imports of steel and aluminium from Canada to which Ottawa responded with measures of its own a month later.

Relations between the two North American leaders have seen highs and lows, but Trudeau said they were now "constructive."
