Washington hastened to assure that the United States will not go anywhere from the Middle East against the backdrop of a message about the upcoming visit of Chinese President Xi Jinping to Saudi Arabia.

U.S. Special Envoy for Yemen Tim Lenderking said diplomatic visits by other world powers to the region should be expected, noting that the U.S. reaffirmed its commitment to the region since Biden's visit in July and the main message the president has brought to the region is that that the United States is not going anywhere, Lenderking told CNBC.

The Chinese leader is reportedly due to arrive in Saudi Arabia next week for a meeting with Crown Prince Mohammed bin Salman as Beijing and Riyadh seek to strengthen ties. The Chinese Foreign Ministry has neither confirmed nor denied these reports.

Jinping is expected to be received in the Saudi kingdom with all the pomp and fanfare, while Biden has been given a much more subdued reception.

However, Lenderking insisted that the US maintain a "vital" presence.

The United States is a vital partner not only for Saudi Arabia, but for every country in the region, he said.

America can be counted on to remain as a pillar of nations and their security. This is an American priority, he added.
