Prime Minister Narendra Modi launched the "Make in India" campaign on September 25, 2014 to boost manufacturing and attract foreign investors to India. The campaign focuses on 25 key sectors and 24 identified manufacturing cities, offering subsidies up to 10% for production of equipment reducing pollution or energy. It aims to simplify decision making and resolve issues within 48 hours through a digital campaign to help foreign investors, take a proactive approach, and ease business regulations to strengthen India's manufacturing sector. Key challenges include existing regulatory clearances, high tax rates, supporting small and medium enterprises, and increasing imports and research and development to compete with manufacturing powerhouses like China.
