Upon assuming the position, Lang was appointed by Bennett and then Finance Minister Yair Lapid to head a committee tasked with increasing competitiveness and removing barriers to imports. The recommendations have since been approved by the government, including: benefits for importers that would enable to them to diversify products and prices, while forcing importers and manufacturers to be more competitive.

Lang has also led, together with the Chief Scientist at the Ministry of Economy and Industry and Ministers Bennett and Deri, the establishment of the Israel Innovation Authority in January 2016, which is the central government body supporting innovation in Israeli industry.

In addition, Lang has led a range of reforms in the field of standardization; promoted competition in the meat and cheese markets; advanced innovation and competitiveness in Israeli industry; expanded Israel’s foreign trade in new markets; promoted foreign investments in Israel – first and foremost expanding the activity of Intel in Israel; promoted innovative solutions in the field of financing and credit to bolster small and medium businesses; and expanded activity in the field of employment to better integrate sectors with low participation rates in the workforce.

Israeli Minister of Economy and Industry Eli Cohen thanked Lang for his service at the Ministry of Economy and Industry over the past four years – a period of significant challenges in the fields of management, regulation and governance. “The Ministry of Economy and Industry presents a challenge for every director general who wishes to help Israeli industry flourish, increase employment and advance the economy while preparing it for the significant domestic and international challenges that lie ahead. Lang's extensive term as director general of the Ministry, the many fields in which he has been active and promoted, his thoroughness, professionalism and humility, side by side with his enormous success, all testify to the dedication he has shown towards all elements of the Israeli economy: to industrialists, consumers, companies, manufacturers, exporters and to the workers themselves. I wish Lang great success and I am certain that he will continue to contribute to the Israeli economy in the future.”
