The 3,500-square metre centre employs 80 engineers. Yazaki has had a branch in Croatia since 1999.
The centre contributes to the development of high tech industry, which Croatia needs, Grcic told reporters.
He said the centre was for now just testing car components but did not rule out the possibility of their production in the future. He hoped that in its development plans Yazaki would choose Croatia as a location for manufacturing.
Grcic said Croatia was interested in such cooperation and that Yazaki representatives would be acquainted today with ideas, possibilities and locations for such an investment.
Yazaki representatives would not say how much the company invested in the testing centre in Zagreb but said they had manufacturing facilities in Romania, the Czech Republic, Slovakia, Bulgaria and Turkey.
Yazaki Europe CEO Masaaki Yoshizawa said the Zagreb centre was expected to follow the corporation's guidelines to keep up with the world and society's needs. Neither he nor the director of Yazaki's company in Croatia, Ranko Resman, wanted to comment on the possibility of opening a production plant in Croatia.
Yazaki has about 150 branches in nearly 40 countries, employing about 250,000 people. Owned by the Yazaki family, it is the world's leading manufacturer of electric and electronic components for the auto industry.
