Argentine President Cristina Fernandez has postponed a visit to China scheduled for next week for domestic reasons, the Foreign Ministry said on Wednesday.
China and Argentina have close business ties. Argentina is one of China's three largest suppliers of soybeans, along with Brazil and the United States.
"Because of domestic reasons in Argentina, President Cristina Fernandez has postponed a visit to China set for Jan. 25-28," Chinese Foreign Ministry spokesman Ma Zhaoxu said in a statement posted on the ministry's website (www.mfa.gov.cn).
He did not elaborate.
Meanwhile, local media said, Kirchner has cancelled all foreign trips over fears that the country's vice-president, who has openly joined the opposition, will seize power.
Kirchner was quoted by media reports as saying she could not leave power in the hands of Vice-President Julio Cobos, who had recently joined opposition forces.
"As the president, I bear political responsibility for what is happening in Argentina in any case. I cannot leave the country for a long period when the vice-president is not performing his duties delegated to him by the people," she said.
Fernandez sacked Central Bank President Martin Redrado by decree earlier this month, but a day later a federal judge ordered his reinstatement. The same judge also issued an injunction blocking the transfer of reserves to state coffers.
