Toyota Motor Corp. said Wednesday that it posted a record ¥1.27 trillion operating profit for the first half of business 2007, largely on the back of robust sales in China, Russia and other emerging markets.

The weak yen also helped boost profits.

The company's operating profit for the six months that ended Sept. 30 jumped 16.3 percent from a year earlier. Net profit surged 21.3 percent to ¥942.4 billion, while sales rose 13.4 percent year-on-year to ¥13.01 trillion. Operating profit, net profit and sales all marked record highs for half-year figures, the automaker said.
