BEIJING - China's index of export container transport remained flat for the past week, according to the Shanghai Shipping Exchange.

The average China Containerized Freight Index (CCFI) stood at 823.83, the same as a week earlier, according to the exchange.

The sub-index for Australia/New Zealand service led the increase with a week-on-week growth of 6.7 percent, followed by those for west coast America and the Persian Gulf/Red Sea routes, which edged up 3.3 percent and 2.1 percent, respectively, from the previous week.

The sub-index for Japan and Mediterranean routes led the fall by both dropping 2 percent from the previous week.
