Addressing queries put forward by the media, including that of Mirror Business at a press briefing, the IMF reiterated that although the staff-level agreement on a four-year EFF programme was reached, the initial disbursement of the programme will only come after the board meeting.
IMF Deputy Director (Asia and the Pacific) Anne-Marie Gulde-Wolf said the disbursement of IMF financing was “preconditioned on the authorities taking certain prior actions on which they are already working. And importantly, on reaching a solution on the debt situation so far”, the Daily Mirror reported on Monday.
As the island nation’s debt was assessed as unsustainable at this stage, the IMF official shared that for the IMF executive board to approve it will need two specific financing assurances.
The first would be from official bilateral creditors, where the fund requires assurances that debt sustainability will be restored. The second assurance is to establish there are “good faith” efforts underway to deal with private sector debt.
Sri Lanka is currently working with its legal and financial advisors on this debt element, the Mirror said.
With regard to the timeline, Gulde-Wolf said it was difficult to be specific in this regard since the process of debt negotiations usually takes time.
IMF’s experience from its member nations in this regard was that the timeline differs depending on who the creditors were and what is involved.
“We certainly are supporting the process as much as we can. And we hope that everybody can work expeditiously to get a process underway, and discussions have been starting, including with the support of all bilateral creditors that are involved,” the report quoted her as saying.
The International Monetary Fund (IMF) said that Sri Lanka is and will remain a middle-income country even after a decline in the Gross Domestic Product (GDP).
The Fund is currently working closely with the World Bank (WB) and the Asian Development Bank (ADB) on programmes for Sri Lanka.
Sri Lanka is expecting to raise up to US$ 2.0 billion worth of bilateral loans collectively from the ADB), the World Bank and other multilateral lenders as bridge financing after country secured programme support from the Fund, according to President and Finance Minister Ranil Wickremesinghe.

二 | 这个推进剂飞船将会部署在地球同步轨道,也就是距离地球3.6万公里的高度上。据报道,这个飞船的设计基于OrbitFab公司最新款的“Sherpa OTV”太空货运飞船设计。该公司尚未披露这个推进剂飞船的存储容量,不过Sherpa货运飞船目前公开的数据显示,这一飞船能够运载几百公斤的推进剂“联氨”,外部飞船可以通过微小的接口进行对接,然后完成太空中的“加油”。据悉,Tanker-002的设计有多个看点,除了全世界第一个地球轨道推进剂存储飞船之外,它的体积很小,上述两家公司如何进行设计以及把它准确发射到地球同步轨道,将值得关注。美国宇航局已经制定了让宇航员重返月球、并且建立永久科研基地的计划,而许多民营太空公司将参加这一计划。在2022年晚些时候或是2023年初,SpaceX公司的猎鹰九号火箭将会把美国休斯顿Intuitive Machines公司的IM-2月球着陆器发射到月球上(并非运载宇航员)。据悉,Tanker-002飞船将会跟随IM-2着陆器一同发射,在升空4小时之后完成分离,稍后将会进入到地球同步轨道上。

三 | IM-2着陆器将会飞往月球,进入环绕月球轨道,并且逐步降低高度,直到在月球表面着陆。

四 | 着陆时间刚好是Tanker-002计入地球同步轨道的时间。需要指出的是,Tanker-002推进剂存储飞船目前还只是一个验证概念的产品,技术尚未完全成熟。

五 | 对于OrbitFab公司来说,在未来第一个太空飞船“空中加油”客户出现之前,他们首先需要解决各种技术难题。因此,在这一次飞行中,Tanker-002虽然会进入地球同步轨道,但是目前在太空中飞行的飞船并无法通过它来加注燃料。据悉,Tanker-002体积重量小,未来主要的服务对象是小型卫星,而小型卫星市场目前还处在研发的初期,尚未普及。据报道,OrbitFab公司已经引发了太空行业的关注,并且从美国两大军工巨头洛克希德马丁公司和诺斯罗普格鲁曼公司获得了投资。在推进剂存储飞船上,他们还需要开发完善,未来或许能迎来客户和回报。
