Chinese to English Bus/Financial Finance (general) Company name 經友

I'm translating a Chinese article about the Japanese aerospace industry in the 1990's, and this company appears as "经友公司" (I think it would be 經友 in Japanese kanji). I think it's a financial company, since the other companies mentioned in the same sentence are. 經 has many readings in Japanese and I can't find any references to a company with any of them. My Japanese is pretty rudimentary so I need some help figuring this out.

Source sentence: 至于贸易合作公司方面，我们也不仅局限于经友公司，我们还将同丸红、伊藤忠、日商岩井和三井等公司进行业务联系。

My translation: In terms of trade facilitation companies, we are not limited to ???; we will also contact companies such as Marubeni, ITOCHU, Nissho Iwai and Mitsui about this matter.
