International stocks trading in New York closed higher on Monday.

The BNY Mellon index of American depositary receipts rose 1.3% to 144.56. The European index increased 1.1% to 145.56, the Asian index improved 1.3% to 149.66, the Latin American index rose 2.9% to 190.92 and the emerging markets index increased 2.1% to 240.16. Alibaba Group Holding Ltd. (BABA) was among the companies with ADRs that traded actively.

Alibaba is making its biggest bet yet on the staid world of bricks-and-mortar retailing, as the e-commerce giant spends $4.63 billion to join up with an electronics chain, Suning Commerce Group Ltd., which once struggled to cope with Chinese consumers shifting to the Internet. Alibaba's ADRs rose 2.1% to $80.47.

ADRs of JD.com Inc. (JD) fell 6.3% to $30.06 as Alibaba's tie-up with Suning allows the e-commerce giant to set its sights squarely on rival JD, whose core business has long been consumer electronics.

Investors drew encouragement after negotiations over a third bailout for Greece appeared to advance over the weekend. Greece's Athex Composite index closed 2.1% higher, although it is still down sharply since it reopened last week after a five-week hiatus.
