China has cut its annual economic growth target to a range of 4.5%-5%, the lowest expansion goal since 1991 as it grapples with challenges both at home and abroad.

It is the first time the target has been lowered since it was cut to "around 5%" in 2023. A target was not set in 2020 due to the pandemic.

The details were released during China's biggest political gathering, known as the "two sessions", alongside the release of some details of the 15th Five Year Plan for the world's second largest economy.

Beijing aims to reshape its economy as it faces issues like weak consumption, a shrinking population, an ongoing property crisis, global trade tensions and an energy crunch due to the Iran war.

One China analyst told the BBC that the lower target gives China "more room to manage the economy" without being forced into making huge financial commitments just to hit a precise goal.

"China has used flexible targets before, particularly during the pandemic, but it's not the norm," Jason Bedford from the East Asian Institute research group added.

The two sessions event, which began on Wednesday and usually runs for at least a week, brings the country's leaders together for back-to-back meetings.

Details of China's gross domestic growth (GDP) target and its objectives under its latest Five Year Plan were included in a 46-page report published by Premier Li Qiang, seen by the BBC.

The full text of the plan, which will outline China's economic development objectives to 2030, will be voted on during the closing day of the gathering.

It is expected to be released by state media one or two days later.

Li told delegates that the Five Year Plan will include investments in innovation, high-tech industries, scientific research and more efforts to boost household consumption.

His comments underline Beijing's concerns that weak domestic consumption makes the country too reliant on exports, as well as highlighting its ambitions to upgrade the country's manufacturing industries.

The report outlines plans for more than 100 major projects over the next five years to expand China's industrial capacity, with a focus on science and technology, transportation and energy.

Beijing also made clear its ambitions to be a global technological powerhouse, with plans to roll out artificial intelligence (AI) tools across key industries.

China aims to lead a green energy push, reducing carbon emissions and improving environmental protection, Li wrote.

The country will also build a "childbirth-friendly society" as it addresses concerns over employment, education and healthcare, the report said.

China faces an ageing population and falling birth rates, complicating Beijing's plans to boost its economy.

In January, official figures showed that China hit its 5% economic growth target for 2025 as a whole. But Beijing also said economic expansion had slowed to 4.5% in the last three months of the year, weighed down by weak domestic spending and a long-running property crisis.

More than two-thirds of China's provinces have scaled back their growth ambitions, either lowering targets or shifting language from aiming higher than a certain rate to targeting "around" that level.

Zhou Zheng, a policy analyst at China Macro Group, said Beijing's new growth target reflects that it is "being realistic" as it deals with complex domestic challenges and a difficult global trade environment.

China's economic growth still marks a "great achievement" given it has been simultaneously tackling major issues that are deeply interlinked and will take time to solve, Zhou said.

But Georgetown University researcher Ning Leng said China's growth figures should be taken with "a grain of salt", as other data suggests a weaker economic picture.

The crisis in China's property sector has hit the country hard and is a key reason for its domestic consumption being weak, she added.

The real estate market once accounted for nearly a third of the Chinese economy and was a key source of income for local governments - many of which now have huge debts.

The industry's problems have also led to layoffs and pay cuts across the country.

Manufacturing and exports have helped support China's economy, recording the world's biggest-ever trade surplus last year - the value of goods and services sold abroad compared to its imports - of $1.19tn (£890bn).

But has means China has become particularly reliant on exports to plug the gaps, which is a weakness the US can sense, Ning said.

US President Donald Trump's tariffs have put further pressure on China's export-reliant economy.

The country has responded by pouring huge resources into redirecting trade to other countries to ensure its products can be sold, sustaining its manufacturing sector, said Ning.

Trump is expected to visit China in April and meet President Xi Jinping for their first face-to-face talks this year.

Meanwhile, the US-Israel war with Iran means Beijing has now lost two key sources of cheap oil this year.

It also can no longer access Venezuelan oil after the US seized President Nicolás Maduro in January.

But Beijing has highlighted that it is far less dependent on fossil fuels as it has for several years been transitioning to renewable energy.
