A/HRC/30/3 49. China welcomed the comprehensive measures to enhance social protection and to ensure that the elderly and others had an adequate standard of living. 50. The Congo was concerned that conventions protecting the rights of migrant workers had yet to be incorporated into national legislation. 51. Costa Rica noted the progress made. 52. Croatia identified the right to peaceful assembly and freedom of expression as the most urgent issue. 53. Singapore noted the adoption of legislation on trafficking in persons in 2012 and the implementation of related policies. 54. The Czech Republic made recommendations. 55. The Democratic People’s Republic of Korea mentioned the considerable progress made in the implementation of the recommendations from the first universal periodic review. 56. Belarus outlined the priorities of the Ministry of Internal Affairs. The operations of the police in detaining persons, using physical force, firearms and other means was strictly regulated in law. Detained persons had the right to judicial examination of the legality of their detention. The law also allowed people to submit complaints about the behaviour of police officers; 6,000 such complaints had been received in 2014, which represented a 10 per cent reduction from 2013.

They also thoroughly investigated all complains of torture or inhuman treatment. 58.
