WASHINGTON/TAIPEI, May 22 (Reuters) - The U.S. and Taiwan have not yet made concrete plans for talks between their presidents, four people familiar with the matter said, despite U.S. President Donald ‌Trump's suggestion he might speak soon with Taiwanese President Lai Ching-te about the island’s defenses.

Trump’s Republican administration authorized an $11 billion weapons package for Taipei in December, but it has yet to move forward. American lawmakers also approved a separate $14 billion arms sale to Taiwan in January, though the deal can’t proceed until Trump formally submits it to U.S. Congress.
