June 3 (Reuters) - Futures tied to Canada's main stock

index fell on Tuesday, mirroring Wall Street peers, as concerns

over erratic U.S. trade policies clouded investor sentiment.

The S&P/TSX index futures were down 0.5% at 6:21 am

ET (1021 GMT).

On Monday, the White House said that U.S. President Donald

Trump and Chinese leader Xi Jinping will probably speak this

week to iron out trade issues, days after Trump accused Beijing

of violating an agreement to roll back tariffs and trade

restrictions.

Markets will closely monitor the call between the two

leaders, as ongoing tariff-induced trade tensions between the

world's two largest economies have caused significant volatility

in global equities and businesses.

Additionally, the Trump administration pushed countries for

their best trade offers by Wednesday, a sign that trade

negotiations were on the horizon.

Meanwhile, the Paris-based Organisation for Economic

Cooperation and Development (OECD) trimmed its global growth

outlook and said the trade war was taking a bigger toll on the

U.S. economy than before.

The news comes ahead of the Bank of Canada's interest rate

decision on Wednesday.

Concerns over how Trump's tariffs would be implemented after

they ran into legal hurdles last week still prevailed after the

administration asked an appeals court to pause a second court

ruling.

On Monday, Prime Minister Mark Carney met with provincial

leaders to expedite mining and energy project approvals and

reduce Canada's economic dependence on the U.S.

In commodities, oil prices steadied, while gold pulled back

after nearing a four-week high earlier in the session.

Copper prices fell as factory activity in top metals

consumer China missed expectations.

Canada's commodity-heavy main stock index climbed on Monday,

as gold and energy stocks edged higher.
