More than 600,000 Rohingya are languishing in Bangladeshi refugee camps after fleeing a brutal Myanmar army campaign launched in late August.
The UN says the scorched-earth operation, which has left hundreds of villages burned to ash in northern Rakhine state, amounts to ethnic cleansing.
Bangladesh, which already hosted some 250,000 Rohingya before the current exodus, wants the latest arrivals to return swiftly and is keen to enlist help from China, a staunch ally of Myanmar.
"When the issue of exodus of displaced Myanmar nationals was raised, the Chinese Foreign Minister stated that as a friend China will help resolve the issue and will not be partial to any side," Bangladesh foreign ministry said in a statement after the talks.

The statement added Wang stressed the "importance of continued consultations and dialogue between Bangladesh and Myanmar on the issue."
No details were given on what concrete steps Beijing might take.
Myanmar has faced growing international anger over its treatment of the Rohingya but China has helped shield the country from censure.
According to Bangladesh's private news agency UNB, Wang held a briefing for a small number of local media at China's embassy in Dhaka where he said Beijing supports "a proper solution of the problems through bilateral channels".
But he warned against further moves at the UN to criticise or punish Myanmar.
Wang is the first of a host of foreign ministers from Asia and Europe who are visiting Bangladesh for talks on a refugee crisis that has left the impoverished nation reeling.
Refugees are penned inside vast, squalid camps, and UNICEF estimates that 25,000 children are suffering from severe malnutrition that could easily become a major killer.
The ministers will also meet Bangladesh Prime Minister Sheikh Hasina.
Bangladesh and Myanmar have agreed in principle to begin repatriation of the Rohingya but are still tussling over the details.
Yet on Thursday Myanmar's powerful army chief distanced himself from any suggestion of a quick return. The Rohingya, he said, could only return if Buddhist citizens accepted them -- a highly unlikely scenario given that the minority are so widely loathed and ostracised inside Myanmar.
