Meteorological departments of China attach significance to international cooperation on disaster preparedness and actively provide relevant meteorological services for countries along “Belt and Road” territories. As earlier as 2011, CMA donated satellite data reception facilities to a handful of countries in Asia. In June, 2015, expert team from CMA went to Bangladesh Meteorological Department to carry out on-site technical services. In May, 2018, NMC spearheaded the technical training oriented towards technical experts from Bangladesh. (May. 20)
