SHANGHAI (Reuters) - Equity markets in Asia faltered on Wednesday amid losses in South Korea and uncertainty over China's plans for further stimulus as the economy shows signs of regaining its footing.
MSCI's broadest index of Asia-Pacific shares outside Japan was 0.3 percent lower, erasing early gains in the wake of record closing highs on Wall Street overnight.
European indexes were also expected to weaken.

"Texas Instruments has published some good results but has poured a little bit of cold water on what's going to happen in the second half of the year," said Frank Benzimra, head of Asia equity strategy at Societe Generale (PA:SOGN).
Chinese equities flitted between gains and losses as investors debated whether Beijing would slow the pace of policy easing following stronger-than-expected first-quarter economic growth.
