There are also reports that China wants another round of talks before signing what Trump last week called "a very substantial phase one deal" that included China buying US$40-50 billion ($63b-$79b) of US farm products and the US cancelling tariff increases due to take effect this week.

"In particular, the board was a little worried that cutting the policy rate further could boost GDP growth by more than anticipated, given that the housing market and the mining sector had turned the corner."
