Our weekly roundup of urban, economic and environmental news from across the globe.

India launched a campaign called “Make In India” to challenge China as the world’s manufacturing hub. By Friday, #MakeInIndia was the second-highest trending topic on Twitter.

Medellin, Colombia blew up four high-rise apartment buildings that were deemed unsafe after one in the complex collapsed last year, killing 12.

Brazil, home to the world’s largest rainforest, refused to sign a pact that would have stopped deforestation by 2030.

Hong Kong’s 17-year-old leader of the massive student protest against Chinese rule was accused by a Beijing newspaper of having government connections.
