He also attaches special significance to relations with India".
The two also had "very friendly and frank exchange of views" over the dinner Monday night.
Obama and Singh had met around four times - during the dinner Monday night, at the East Asia summit Tuesday and the Retreat for East Asian leaders later, and a brief face to face meeting, said official sources.
Menon met his counterpart Tom Donilon for about 90 minutes earlier in the day. The two discussed bilateral and regional issues, but no details were given.
Obama had flown in to Cambodia from Thailand and Myanmar. His visit to Myanmar and Cambodia are a first for any US president and marks the growing importance the US attaches to engaging with countries in the Asia Pacific.
