China International Marine, the world's largest manufacturer of shipping containers by output, said its net profit for the six months ended June 30 was US$134.17 million, up from $121.42 million a year earlier, according to Chinese accounting standards.
Revenue more than doubled to $3.12 billion from $1.38 billion.
The company said it expects net profit for the January-September period to rise 150 to 200 percent from a year earlier, partly because of a low comparison base a year earlier.
China International Marine had a net profit of $114.06 million in the nine months ended September 30.
