A |     China and Tanzania are set to deepen financial cooperation and expand the use of the Chinese currency renminbi (RMB), or the yuan, in cross-border trade and investment, as the Bank of China on Tuesday hosted an RMB internationalization roadshow in Tanzania.    The event, the 10th stop of the Bank of China's 2026 global use of RMB roadshow series, brought together more than 140 representatives from the Chinese Embassy in Tanzania, the Bank of Tanzania, major financial institutions and businesses from both countries to explore new opportunities for RMB cooperation.    Speaking at the event, Chinese Ambassador to Tanzania Chen Mingjian said growing economic and trade ties between the two countries had created increasing demand for efficient, convenient and low-cost RMB-based settlement and financing services in Tanzania.    "Bilateral trade between China and Tanzania reached 11.28 billion U.S. dollars in 2025, exceeding 10 billion U.S. dollars for the first time," Chen said, adding that trade reached 6.48 billion dollars in the first half of 2026.    China has remained Tanzania's largest trading partner and a major source of foreign direct investment for many consecutive years, she said.    Yun Yi, deputy general manager of the clearing department at Bank of China Head Office, said the bank would continue to leverage its global network and role as a major provider of cross-border RMB services to support the wider use of the Chinese currency in China-Africa trade and investment.    He said the bank would further enhance RMB financial services and facilitate practical cooperation across a wide range of sectors, contributing to higher-quality China-Africa economic and trade cooperation.                    。

人民网北京9月14日电 (记者赵竹青)9月13日21时18分,中国文昌航天发射场,长征七号改运载火箭(简称“长七A火箭”)点火升空,成功将中星1E卫星送入预定轨道。该卫星可为用户提供高质量通信广播电视服务。该火箭由中国航天科技集团有限公司所属中国运载火箭技术研究院(以下简称“火箭院”)抓总研制。据了解,长七A火箭是我国新一代中型运载火箭的主力构型,是在长征七号运载火箭和长征三号甲系列运载火箭三子级基础上、通过组合化设计形成的高轨三级液体捆绑式运载火箭,地球同步转移轨道运载能力不低于7吨,填补了我国运载火箭地球同步转移轨道5.5至7吨运载能力的空白,可适配直径4.2米和3.7米两种整流罩,具备一箭一星和一箭双主星发射能力。长七A火箭主任设计师魏远明介绍,本次执行任务的长七A遥五火箭,采用整流罩直径4.2米的构型,全箭高度60.1米,与2021年3月12日发射的遥二火箭高度一致。

C | 长七A火箭作为我国首型采用助推器与芯一级集束式分离技术的捆绑火箭,相比通常先分离助推器、再分离芯一级的方式,减少了一次分离环节,使火箭捆绑连杆结构更加简化。同时,集束式分离也减少了一个助推器落区,整个组合体都在一个落区内,更加有利于控制火箭残骸落区。此次是长七A火箭第四次执行发射任务,火箭状态正在逐步固化,同时为进入高密度发射阶段提前准备。魏远明介绍,型号队伍针对火箭技术设计进行了多项优化改进,在确保测试覆盖性的前提下,通过优化流程顺序、并行工作、合并测试等方法,将发射技术流程由32天缩减至26天。不仅如此,根据高轨卫星整体发展态势,以及高轨卫星配置大尺寸天线的迫切需求,长七A火箭未来还将研制5.2米整流罩的新构型,进一步提高火箭的任务适应性。
