Lenovo, the world’s No. 4 PC maker, is concerned about the impact of the Japan earthquake on its supply chain in coming months.

At an event in Shanghai on Thursday, Lenovo Chief Executive Officer Yang Yuanqing told reporters that immediate problems are minimal.

“In the short term there won’t be much impact,” Yang said, according to Reuters. “We are more worried about the impact in the next quarter.”

The Economic Times also reported Yang’s concerns.

Lenovo operates a lab in Yamato, Japan, and maintains its headquarters for Japanese operations and sales in Tokyo. It is in the process of forming a joint venture with Japan-based NEC that will be the largest PC provider in that country.

However, Lenovo does rely in Japan firms for parts, such as semiconductors.

Lenovo, which bases most of its operations in China and operates its headquarters in Morrisville, is just one of many companies concerned about the impact of factory shutdowns in Japan as a result of the quake.

Lenovo has hundreds of employees in Japan, according to a company spokesperson.

The company is launching a $1 million relief fund for victims of the quake. (Read here for more details.)
