Executives from computer makers and other technology firms show growing concern that the unfolding disaster in Japan can disrupt their global supply chains in coming months.
Computer parts makers Toshiba and Hitachi both said they face month-long halts in production of liquid crystal displays at plants in Japan, devices used in mobile phones.
Yang Yuanqing, CEO computer firm Lenovo, told reporters in Shanghai he is worried about the impact on the global supply chain of technology components in this year's second quarter. However, he also said "in the short term there won't be much impact," Reuters reported.
Taiwan's government says it may cut tariffs on electronic components if shortages develop. Plants there make computers and other electronic products for major brands.
That supply chain concern is also growing about the large flow of automobile parts out of Japan.
The intermodal shipping industry could also be affected, since both auto parts and high-tech products are shipped in containers.
The concerns are spreading not only due to damages sustained by factories in Japan by last week's earthquake and tsunami, but by the expanding nuclear threat from failing reactors and by significant power disruptions across the country.
Uncertain power supplies for plants and disruptions to daily lives of workers are making it hard for managers to plan their production schedules even when factories or those of their suppliers are not damaged.
