TOKYO (AP) – Peruvian ex-president Alberto Fujimori is attempting to forge a three-group political alliance, the Peruvian Embassy in Tokyo said Wednesday, as part of his effort to win re-election to lead the South American nation.

Fujimori, who fled to Japan in November 2000 as his 10-year-old government crumbled amid corruption scandals, came to Peruvian consular offices in Tokyo on Wednesday to validate his signature on a document joining his political movement with two parties, officials said.

The consular office notarized his signature, but affixed a stamp saying that it did not recognize the document, since Fujimori is barred from political activity because of the myriad of charges against him, the officials said.

“We legalized the signature, but not the content of the document,” said Hector Matallana, Peruvian consul general in Japan.

Fujimori faces 21 charges ranging from abuse of power to sanctioning a paramilitary death squad. The Peruvian Supreme Court dismissed a 22nd charge against him, of corruption, two weeks ago, citing a lack of evidence.

Fujimori has vowed to return to Peru to run for re-election in next April’s elections, despite the charges against him and a standing congressional ruling, upheld by Peru’s Constitutional Tribunal, prohibiting him from holding public office until February 2011.

The document Fujimori signed on Wednesday showed he was creating an alliance between his support group, Si Cumple, and two other political parties: Cambio 90 and Nueva Mayoria, Matallana said.

The move is aimed at allowing the three groups to present candidates on one list, but Peruvian officials in Tokyo said the ban would stop Fujimori from taking a leadership position in the alliance.

“This has nothing to do with his political rights – he’s banned,” said Jacques Bartra, the embassy minister.

Peruvian prosecutors have also petitioned Japan to extradite Fujimori so he can face the charges against him. But the disgraced ex-president, the son of Japanese immigrants, has been shielded from extradition by Japanese citizenship granted after his arrival.

Tokyo has repeatedly said Japanese citizens can’t be extradited under Japanese law.
