To a question about political comments regarding HAL losing potential jobs because of the Rafale deal, Ziegler questioned whether HAL has made any comments about losing jobs.
"Did they tell you that they have lost jobs?...
I don't know what potential jobs are, he said, as he pointed out that there is a 50 per cent offset clause in the Rafale contract, which is about four billion Euros or about Rs 300 billion that is going to be invested in Make in India.
"That's huge (amount) and there will be room for hundreds of companies, including HAL, which has had a very fruitful historical cooperation with French companies," he added.
The Ambassador also noted that all major French companies would be participating in Aero India, scheduled for February 20-24 in Bengaluru.
"Our companies will be there...I cant tell you how many, but all our major companies will be there," Ziegler said.
Stating that almost all major French players have been investing in India for years now, he said, "we have had long cooperation with India. Companies like Airbus, Thales, Dassault have been sourcing in this country.
Transfer of technology has been happening for decades."
It's very very "historical cooperation" between India and France, he said, adding that we have not waited Make in India to be launched.
"Our companies have been making in India for decades now. Transfer of technology has been happening," he said.
The party has alleged that the government was helping the Anil Ambani group get a contract worth Rs 300 billion from the deal.
