cities legacy relationships journ.

[MarinaNikolaevna]

Добрый день, уважаемые коллеги!

Пожалуйста, помогите перевести или понять следующее предложение: Company B, which supplies the integrated AZX system, cites the legacy relationships of its larger siblings as factors in its involvement.
.

Слово встречается в следующем контексте:
For some of the Western contractors, the Russian market offered not only an opportunity for new growth, but also a chance to capitalise on existing relationships. This was certainly the case for members of the XXX group. Y's previous relationship with Z undoubtedly helped oil the wheels of the A joint venture, while Company B, which supplies the integrated AZX system, cites the legacy relationships of its larger siblings as factors in its involvement

Заранее спасибо
