The Fortescue Metals Group Limited (ASX: FMG) share price is suffering on Thursday.

At the time of writing, the Fortescue share price is $17.60, 1.68% lower than its previous close.
For comparison, the S&P/ASX 200 Index (ASX: XJO) is currently up 0.11% while the S&P/ASX 200 Materials Index (ASX: XMJ) is slipping 0.77%.
So, what could be going wrong for ASX 200 iron ore goliaths today? Let's take a look.
What's weighing on the Fortescue share price today?
The Fortescue share price is in the red today alongside those of BHP Group Ltd (ASX: BHP) and Rio Tinto Limited (ASX: RIO). They're each down between 1.6% and 2.8% right now.
And while some of Rio Tinto's downfall could be to do with a near-$1 billion tax settlement, the heavy weights' suffering doesn't have an obvious explanation.
Particularly, as iron ore futures lifted 0.9% overnight to reach US$104.01 a tonne.
One reason behind today's tumble could be profit taking. The materials sector leapt 2.5% yesterday with the Fortescue share price among its leaders. The stock rose 5.23% on Wednesday.
Additionally, it could be impacted by reports of China's new national iron ore company. A new entity, dubbed China Mineral Resources Group, has been set up to snap up iron ore to supply Chinese steel producers, reports ABC News.
The news could birth concerns that a body charged with consolidating iron ore purchases could force down iron ore prices.
However, the publication reports insiders are unconcerned for now. Indeed, Fortescue boss Andrew 'Twiggy' Forrest brushed off concerns of a 'Chinese ore cartel' last month.
