In the near term, it is highly unlikely that Chinese-made engines would be adopted by Boeing or Airbus, given certification barriers, supply chain integration challenges, and broader geopolitical considerations. As a result, the primary initial market would be China’s domestic commercial aircraft programs.

However, the scale and timing of that demand remain uncertain. Early production volumes for programs such as the C919 are relatively limited, and initial fleet sizes alone may not be sufficient to amortize the substantial research and development costs associated with modern turbofan engines. This raises questions about the commercial viability of such programs in the absence of broader international adoption.

China’s civil aviation industry is still in a relatively early stage of development. The C919, its first domestically developed narrow-body jet, has completed test flights and entered initial service with Chinese airlines. At present, it relies on engines supplied by GE. A critical milestone for the program is obtaining international airworthiness certification, particularly from U.S. and European regulators, which would enable broader global operations and improve export prospects.

If such certifications are achieved, potential demand may emerge from developing markets, including Southeast Asia and parts of Africa. Nevertheless, penetration into North American and European airline fleets would likely remain limited for the foreseeable future, even if existing Western-supplied engines continue to be used.

Recent export control measures—such as U.S. restrictions on the sale of certain engine technologies—highlight the extent to which geopolitical factors can influence supply chains in the aerospace sector. These constraints have, at times, affected delivery schedules for aircraft programs like the C919.

In this context, China’s push to develop indigenous engine capabilities can be understood as a strategic response to external dependencies. Similar dynamics have been observed in other high-technology sectors, including semiconductors and advanced computing hardware, where supply chain resilience and technological self-sufficiency have become increasingly important policy objectives.

says "The unusually abrupt decline in cases by April 2020 was attributed to the effects of widespread social distancing and lockdowns aimed at COVID-19"

Is there any possibility that the cases are counted in COVID-19 after April 2020 ?
