Chinese President Xi Jinping began a visit to Saudi Arabia on Wednesday that Beijing said marked its biggest diplomatic initiative in the Arab world, as Riyadh expands global alliances beyond a long-standing partnership with the West.

The meeting between the global economic powerhouse and Gulf energy giant comes as Saudi ties with Washington are strained by U.S. criticism of Riyadh¡¯s human rights record and Saudi support for oil output curbs before the November midterm elections.

The White House said Xi¡¯s visit was an example of Chinese attempts to exert influence, and that this would not change U.S. policy toward the Middle East.
