NEW DELHI, May 30 (Reuters) - Saudi Arabia is set to

place orders for billions of dollars of Airbus jets as

the kingdom balances suppliers in its quest to match the

aviation growth of Gulf neighbours, industry sources said.

Leasing company AviLease, which placed an order for 30

Boeing 737 MAX jets during a visit to the region this

month by U.S. President Donald Trump, could place a comparable

order for Airbus A320neo jets at next month's Paris Airshow,

they said.
