MELBOURNE, April 9 (Reuters) - London aluminium rallied two
percent on Monday and is expected to rise further on concerns
that sanctions by the United States on aluminium giant Rusal
 could hamper trade in some seven percent of the
world's annual supply of the metal. 
    The United States on Friday imposed sanctions against
Russian businessmen, companies and government officials,
striking at associates of President Vladimir Putin in one of
Washington's most aggressive moves to punish Moscow for a range
of activities.
    Shares of United Company Rusal Plc fell 31 percent
in Hong Kong on Monday after it was included in the new list.

    "Market concerns have that the sanction against Rusal and
its own technical default assessment may lead to supply shortage
in both aluminium and alumina," said Hong Kong broker Argonaut
in a report.
    Rusal produced some 3.7 million tonnes of aluminium in 2017,
about 7 percent of the world's total, Argonaut said. Its annual
alumina production of 11.5 million tonnes was also about 7
percent of the global total, while it produced about 4 percent
of the world's bauxite, the broker said.
    "It is expected that (the aluminium price rise) will
extend further," Argonaut said.
