India aims to tighten rules around the scrutiny of mergers and acquisitions under proposed legislation that could particularly affect global tech firms that do a lot of business there. The proposal is part of an overhaul of India's competition law in a bill that was introduced in parliament on Friday and could be passed as soon as next week. Under current law, the Competition Commission of India (CCI) reviews mergers and acquisitions that surpass thresholds for assets or turnover.
