China and Myanmar have complementary advantages, close economic and trade relations, advancing connectivity, and promising prospects for practical cooperation. China is Myanmar's largest trading partner, export market and source of imports, and is also one of Myanmar's most important sources of investment. According to Myanmar statistics, in the 2018/2019 fiscal year, the total trade volume between China and Myanmar was US$11.36 billion, accounting for approximately 32.5% of Myanmar’s total trade volume. As of December 2019, the Myanmar Investment and Company Administration has approved a total of US$20.935 billion in investment from mainland China in Myanmar, accounting for 25.21% of Myanmar’s total approved foreign investment. According to statistics from the General Administration of Customs, in 2019, the trade volume between China and Myanmar was US$18.7 billion, a year-on-year increase of 22.8%. Among them, China's exports to Myanmar were US$12.31 billion and imports from Myanmar were US$6.39 billion, a year-on-year increase of 16.7% and 36.4% respectively. According to preliminary statistics, Chinese-funded enterprises have opened more than 400 textile and garment factories and upstream and downstream enterprises in Myanmar, creating nearly 400,000 local jobs in Myanmar.
Myanmar was one of the first countries to respond to the “Belt and Road” initiative. State Counselor Aung San Suu Kyi took the lead in establishing the Myanmar “Belt and Road” Initiative Implementation Leadership Committee in 2018 and served as its chairperson. Since then, the leaders of the two countries have reached a consensus on jointly building the China-Myanmar Economic Corridor, which starts from Yunnan, China, in the north and extends through the China-Myanmar border to Yangon and Kyaukpyu respectively. The two governments focused on 12 key areas such as production capacity and investment, transportation, energy, and agriculture, and established special working groups
4月5日，俄罗斯哈巴罗夫斯克市克拉夫丘克市发现放射性污染源，并在局地实施紧急状态。连日来，黑龙江省大气辐射环境自动监测站24小时实时监测γ辐射剂量率并采集气溶胶样品，监测结果处于正常水平，未见异常。

黑龙江省共27个大气辐射环境自动监测站，其中佳木斯市抚远、同江地区2个自动监测站距离哈巴罗夫斯克地区最近，约为60公里和210公里，可24小时实时监测γ辐射剂量率并采集气溶胶样品。4月5日以来，连续自动监测结果显示，辐射值处于正常水平，未见异常。
4月8日，俄罗斯塔斯社文章称，此前曾进入紧急模式的哈巴罗夫斯克工业区现场的辐射背景已恢复正常。4月9日，俄罗斯哈巴罗夫斯克市克拉夫丘克市长签署命令，宣布自10日起解除因发现放射性污染源（为一个工业探伤仪上的铯137胶囊，目前已被转送至专业监管机构）该市局地实施的紧急状态。此事件未对居民健康和周边环境造成不良影响。目前，哈巴罗夫斯克市生产生活秩序正常。
黑龙江省原子能研究院专家介绍，如确定发现的辐射源为“放射源”，该放射源的不锈钢外包壳没有破损，内容物没有散落遗失，并且非其它核材料等核物质，俄罗斯方面已将放射源安全放置在容器中，并送至放射性废物暂存设施中存储情况下，事件发生地辐射数值即会降为正常水平，不会对当地持续产生放射性影响，也不会对人体产生危害。
