Shanghai Port, the world's busiest container port, saw its container volume in June rise 5.7 percent from the previous year, with the growth rate picking up for the second straight month, data issued by the port's operator showed.

Container throughput reached 2.77 million twenty-foot equivalent units (TEUs), down from 2.84 million in May.

The annual growth rate nearly doubled from May's 2.8 percent.

According to economists polled by Reuters, trade data is expected to show annual export growth of 9.9 percent in June and import growth at 12.7 percent.

Shanghai Port became the world's first port to exceed the 30 million TEU threshold in 2011 with a total container throughput of 31.7 million, 9.2 percent more from a year earlier.

Zhuge Yujie, president of Shanghai International Port (Group) Co Ltd, the port's operator, warned in May that growth would slow this year to 2-3 percent as the economy slows. (Reuters)
