KUALA LUMPUR (Reuters) -Malaysia's parliament on Thursday passed a law to better regulate government procurement processes, as rights groups and some opposition lawmakers raised concerns over potential loopholes and a lack of independent oversight. The Southeast Asian country has been seeking to strengthen fiscal management and avoid the massive financial losses linked to corruption cases like the multibillion-dollar 1MDB scandal. It has also long struggled to contain leakage and misappropriation from graft involving public officials, particularly through the awarding of government contracts through negotiations rather than open tenders.
