An anti-corruption watchdog raised concerns about irregularities in the construction of a Bangkok skyscraper that collapsed in an earthquake, killing at least 11 people. The government had threatened to cancel the project due to delays earlier this year. The building, constructed by a Chinese company and a Thai firm, was the only one in Bangkok to completely crumble during the quake. Investigations are ongoing to determine the cause of the collapse, with concerns about sub-standard steel and possible corner-cutting during construction.
