The relationship between the United States and Saudi Arabia seems to be getting shaky lately.
It follows the conflict over crude oil, where President Joe Biden had previously warned of imposing 'action' on Saudi Arabia for its decision to reduce oil production last October.
However, it was responded calmly by the Saudi Arabian government which defended its actions through a diplomatic statement.
Unwittingly, Crown Prince Mohammed bin Salman has personally threatened Washington to fundamentally change the two countries' relationship and impose significant economic measures if the US does so.
This is seen from a confidential document obtained from The Washington Post which reported on the matter.
Although it is not clear whether the threat was conveyed directly to US officials, it indirectly reveals the tension between the two countries.
What's more, Saudi Arabia's relationship with China is also getting closer, which has recently joined China's security bloc, the Shanghai Cooperation Organization (SCO), as a dialogue partner.
Even so, this report is seen to have no impact on the current crude oil trading which is now trading stable due to the weaker US dollar.
In the Asian session, Brent crude oil futures traded little changed at around $75.49 a barrel, while US WTI was at $70.83 a barrel.
