India is joining the global pursuit of some of China’s most valuable assets – its big-spending tourists. With a campaign in 12 Chinese cities this spring, the world’s second-most populous nation hopes to capture the imagination of travelers from the most populated country. The promotion, called “Glimpses of India,” kicked off last month in Beijing with music and dance performances at the showpiece Poly Theatre. In March, India changed the rules to make it easier for Chinese visitors to get visas.
