Another subsidiary of the privately held company is also looking to expand.
Ferrero Germany, which recently decided to allow discount retailer Aldi to sell its products, plans to launch two new brands.
Ferrero Garden and Kinder Joy will be on sale from May this year in a bid to boost sales.

Kinder Joy is also intended to plug the hole left in sales due to Kinder Surprise's absence during the summer months.
To promote the new lines Ferrero has set aside an advertising budget of €240 million making it the biggest advertiser in Germany's confectionery market.
