Sales at the overseas subsidiaries of Japanese manufacturers grew 15.5 percent in dollar terms in the April-June period from a year earlier for the ninth consecutive quarterly rise.

The Ministry of Economy, Trade and Industry said Thursday that a quarterly survey found that sales at 2,677 responding subsidiaries overseas totaled $129.05 billion, up from $124.76 billion in the January-March quarter.

It said the rise was mainly due to brisk sales in electric machinery and transport equipment in Asia.

Sales in China, including Hong Kong, surged 31.6 percent, spurred by firm sales of digital consumer electronics, for the fifth consecutive quarterly expansion of more than 30 percent.
